Software testing services are actually based on the working model specifically developed to provide software development projects with the practices and also elements that allow integration of the product and strategy to ensure that the software complies with the requirements of the business. In addition, software testing services offer all the benefits associated with integrating a testing factory into a development project.
INTEGRATED FUNCTIONAL TESTING Integrated functional testing services are designed to verify and validate that the tested software meets all functional specifications. A full set of specialized test functional tests typically uses black box techniques, scripted-testing, and exploratory testing to identify critical errors. We typically identify over 80% of serious software defects after three test cycles. TEST AUTOMATION Through the automation of some tests, the customer can save time and money in testing certain types of products, especially those that need successive testing systematically. After studying the software, Make IT Work has the expertise to determine the best place to deploy automation, and take care of the definition, development, and implementation of specific scripts that it then runs to find problems quickly. PERFORMANCE TESTING Is your product ready to face the daily load of users it will have after launch? To determine it, Make IT Work offers load, performance or stress tests that quickly find out what your weaknesses are, always taking into account the project objectives. These tests allow our team to generate a series of recommendations that you can then implement to predict expensive system overhead and shutdowns. The greater operational efficiency of the development process. Software companies get the most qualified resources at the right time immediately. Considerable cost reduction. Hiring experts in the area that ensures quality in the work of software testing services since the beginning of development improve the predictability of the schedules and help the delivery of your product becomes a tangible fact. Immediate return of invested amount. Outsourcing allows you to manage a flexible designation of resources compatible with the ups and downs of demand, as well as parallelize the development work during the life cycle. In this way, software testing services can assure the efficient and systematic control of the quality of all type of software with solutions for all type of company and modality of development. In fact, we have already adapted to agile (SCRUM) and formal methodologies and work on all technologies, whether web, desktop, cloud or mobile.

Computers are good at doing repetitive work, and running tests is almost always a repetitive job.
Testing Automation Services will allow you to write the test only once and then, from time to time, a robot will perform all the tests you wrote for your software. Your team builds confidence because automation creates a kind of protection network preventing unexpected results from spreading, giving the team the ability to resolve them before they reach customers. The tests get cheaper and your customer is more satisfied by not finding errors in your product. In the items below, we'll talk about how tests can be organized and what tools, frameworks, and libraries you can use to get started automation. We can separate automated tests into three large blocks that make up the Testing Automation Services. Unitary tests At the base, we have the unit tests. They are many because they are usually easy to build and inexpensive to maintain. An interesting point that we perceive in our journey is that the definition of Unit is different for each company. Someplace as the unit of the system (complete software), others as a module or a service. Here we adopt the concept of Kent Beck and Martin Fowler: The unit of code is a smaller part of the program containing source code. The origin of the name comes from Delphi storing the code in a Unit. For Java, C #, Python, Ruby is the class. Tools for this are many. Depending on the programming language you are using. Below is a short list of the basic tools for you to start doing unit testing on your products. Integration In the middle of the pyramid, we have the integration tests. They are those that cross the unit of the source code. For example, communication between two or more classes through a method, or communication of the software with the database and even other services. These tests are usually a bit more expensive to maintain as there is a dependency between two or more components. Changing one can influence the test of the other. Also, if your test depends on a mass of input data, you must prepare it before the tests and return your database to the original state after the test. The use of Mocks can significantly reduce this interdependence. The tools that are used for these tests are basically the same as those indicated in the unit tests. However, others can be used here as Postman for integration with APIs (services and microservices), DB Unit for integration with the database, among others. Interface and Acceptance At the top of the pyramid are the interface and acceptance tests. They are harder to build and more expensive to maintain because we need all the preparation to run them. They are black-box tests that run the user's full time interacting with the software. There are two fundamental purposes for testing: checking specifications and performing risk management. First, we run tests to verify that everything that has been specified for a product or system is found to be pre-set. If the performance is functional, if the implementation obeys what was requested and the like. Then comes the role of risk management. For both manufacturers and consumers it is important to have the notion that the product in question has little or no probability (if this is possible) of an error that makes it impossible to use.
Verify and validate Verifying and validating a software product is a process that seeks to determine if the system meets its predefined objectives. This is a process that starts early in the software development lifecycle. This is a fundamental process that can be performed by the team that made the product, but is more efficient when performed by people outside the development. Improve the quality The software testing services that we develop is often used in critical areas such as medical diagnostics, air traffic control, space missions, or salary payment (kkk). A bug in one of these applications can cause irreparable loss. Improving the quality of your software is of utmost importance as it helps ensure that the software meets the requested standards. Improve reliability In order to have good software it is necessary that its users have confidence in it. It does not do much good software that does not serve the purposes. An incorrect medical diagnosis can simply mean the loss of life. When purchasing a product the customer wants to be sure that it will be useful. Software developers need to look closely at the reliability of a program to ensure the satisfaction of those who use it. The reliability question is one of the most important aspects in choosing a product. When the product in question is software , reliability and security have to be even greater. Often the customer needs to be sure of the quality of the software to be able to acquire it. Usually the consumer expects to use a particular program and it works as expected without interruptions and failures. Usability and Operability A very important purpose of software testing is to prove that software is useful and accessible. Usability tests usually happen by a select group of users where usage is observed and studied. All aspects are important when it comes to user interaction with software. Observe ease of use, difficulties and problems are recorded and analyzed. Prevent further Bugs The term BUG comes from the year 1945, when a moth was found on a MARK II computer circuit. Anyway, since that time is one of the most detested terms between developers and users. Most errors are usually introduced in the software requirements. It can also be defined as a logical failure of a program, which may cause discrepancies in the expected results, or impossibility of performing a program's functionality. If errors are detected early, they can be prevented from migrating to the next development phase. The earlier you detect the error, the easier your debugging gets, and this can save you many exhausting hours looking for bugs. Consuming two litres of water a day is very important for our health, How many times this suggestion you would have heard? But the quality of the water is being consumed and the level of potability should be ignored by many and people who believe that we use water, and the water is also important for sanitising and also for preparing food, washing clothes and utensils, etc. For the reason, the quality of water in our home’s is important to maintain the proper health of our family members. In order to maintain water clean and bacteria free we can use water filter pitchers in our houses. Which will be very useful and also easy to use. It is very easy to find in supermarkets, general stores and others. A wide variety of bottles and gallons of water, therefore the space occupied by these items, the difficulty in constantly buying them and the cost, is not worth it. That is why the most of the households opt for water filters or pitchers to facilitate access to potable water, but the great difficulty of most of them is at the time of purchase. Filters, Pitchers or purifiers, what is the difference and which one is the best for home? Lets find out. One of the simpler method is using water filters, they are usually perform their work through central candle that retains the impurities. Therefore these filters are able to eliminate dirt from the water without any use of electric power, ideally for anyone who wants to save power. They are generally found in water filter bottles, which is more affordable prices than purifiers. They even remove the chlorine and bacteria content present in the water. It is considered ideal for anyone receiving treated water at our home and uses. Hydros water bottles are best option and also very economical compared to other. Filter has automatic cleaning operation. The purifiers have several extra advantages, as they offer a series of specific water care. In addition to the main filter element, it is common for other levels of purification and technologies that act directly on the extermination of bacteria, such as the violet lamps of some purifiers. Speaking of diversity, the level of water cleaning varies according to the model and manufacturer of the purifier, varying on a scale between P1 (most efficient) and P6 (the most basic). These appliances are also practical because they are attached directly to the faucet or plumbing, increasing up to the available water pressure. With the purifiers it is possible to eliminate excess chlorine and various bacteria from the water. Software testing services are provided by few organisations which deals with all kind of automation testing tools for digital projects.
Selenium is a dense API that allows automation in web applications for major browsers. You can automate using HTML, CSS, or XPATH. The same code is reused in multiple browsers, gaining scale of execution of the tests. It is compatible with several programming languages like Java, C #, Ruby and etc. Allows you to run tests on a virtual machine or through cloud services. Think only of the gain in scale by running the same test scenario in 100 different settings. And to top it off, Selenium was standardized by W3C and became a standard for web testing automation. The Cartesian product of Tests X Devices X Configurations greatly increases the efforts required to standardize mobile applications. With the Appium tool, you can automate one-time functional test cases for Android and iOS and run on the various Devices and Settings. The tool reuses the code standardization of the Selenium tool. Another advantage is the use of scripts on locally or cloud-connected devices. There are several cloud device farm services enabled to run automated tests in Appium. The purpose of performance testing is to ensure and measure application stability under certain conditions of load, stress, availability, latency, and so on. With JMeter, it is possible to generate irregular conditions of peak, overload, and stress. It is possible to authenticate from the traditional HTTP calls that originate from the browser as well as calls to SOA and JSON services. Making sure that transactions and business rules are in place before the first screens are finished is a task to be performed by the SoapUI tool. It is possible to perform the services and API tests. Using the Groovy language and isolating the services layer from the presentation layer, the SoapUI tool makes it possible to identify errors of business rules, communication, or integration between systems. The tool supports JSON, XML, HTML. It also supports "mock" services and performance tests. BDD (Behavior Driven Development) has become a key discipline to increase software testability. It elevates the TDD (Test Driven Development) and the DDD (Domain Driven Development) to a new level, allowing to specify the business intelligence in the code. It goes in line with the idea of testing before the application is ready. Cucumber is the tool that makes it possible to specify the expected behavior of the software during coding and then use these test scenarios to check the behavior. Delivering an application with test intelligence built into the code brings value mainly in regressive and oil tests. Having these tools at hand is already a good target for stakeholders who want to adopt test automation in their digital projects. Several governments in developing countries have been concerned about the issue of computerization of their organs, companies, and society as a whole. This has awakened in organizations the search for tools and methodologies that aid in their processes. Software testing services is the most effective services in these days, where most of the works can be done by tools. Which also reduces our work load.
The software is a set of instructions that are executed in order to produce desired functions and performances. It can also be defined as data structures that allow programs to manipulate information. Or, documents describing operation and use of programs. The software has become important to companies, as a differential of performance and control, which provides competitiveness before the competition. Regarding this referential, development companies are increasingly worried about their engineering, in order to attribute the quality to the products developed. In order to improve the quality of software in general and increase productivity in the development of such products, software engineering has emerged. This is a set of three elements: methods, tools, and procedures that allow the manager to control the development process and, to the professional, provides the basis for building a product with high quality, in a productive way. The methods indicate how to build the product. Involve planning, project estimation, requirements analysis, data structure design, program architecture, algorithm processing, coding, testing, and maintenance. The tools provide automated or semi-automated support to the methods, for each there are support tools. Procedures are the link between methods and tools. They define the application sequence, the products to be delivered, the quality controls and the coordination of changes, and the benchmarks for assessing progress. Therefore, software engineering can be defined as a set of principles for the development of a product with a high level of quality and reliability that works efficiently. For this, the quality becomes the mainframe. Software quality The main purpose of software engineering is to assist in the construction of quality products. Quality is to meet perfectly, reliably (without defects), affordable (low cost), secure and at the right time the needs or requirements of the customer. Quality can also be understood to be in compliance with explicitly stated functional and performance requirements, clearly documented developmental patterns, and the implicit characteristics that are expected of all professionally developed software. Quality is a systematic process that focuses on all stages and produced with the objective of ensuring the conformity of processes and products, preventing and eliminating defects. If in the context of software engineering quality means meeting the specified requirements and the needs and expectations of the customer, ensuring this "quality" is not always as simple as it seems. Generally, implicit requirements are met along the way, sometimes with varied or even incomplete representations, which detract from the product, cause rework, and affect cost and lead times. To avoid these impasses it becomes necessary to incorporate methods and concepts such as "Planning, Control and Quality Assurance" You've probably heard that good products have good usability, but what does this really mean? Usability is determined by the evaluation of criteria such as learning ability, efficiency, memory, error management, and satisfaction. All of these elements can be tested from the usability test. There are few organizations who provide Software testing services
What is the usability test? It is extremely important to expose the user interface to other people. As the design and implementation of the interface progress, you should expose the design to a growing number of reviewers, such as:
The purpose of this exercise is for observers to identify usability issues by looking at this combination of criteria I mentioned above. If the user can quickly learn how the product or service works, be able to use it effectively, the product or service adapts to changes and meets all needs, it will have a good evaluation. Why conduct usability testing? The usability test is a fundamental tool and should be used whenever possible. That's because they help you beyond imagined with issues you often did not even know existed about your product. This is the best way to get into your user's mind and understand their process and perspective. In addition, it is a low-cost alternative, which can be conducted in a relatively short time. What does UX design have to do with this? All! The user experience design or experience design is exactly the field responsible for these usability tests. Within information systems, software testing is extremely efficient in anticipating problems and improving interfaces. Within interaction design, it is always better to know as soon as possible what the strengths and weaknesses of the applications are, to bring the best first version to the market in the time of production available. Understanding of information architecture, user interface, and user experience greatly facilitates efficient usability testing and the use of data collected during the test effectively during the design. Water is one of the most precious possessions that exist in mankind. However, water may also contain microorganisms that eventually cause serious health problems. Luckily today there are solutions to purify water and protect us.
Water filter pitchers are the best way to purify the water and also removes all the bacteria present in the water. Benefits of having a water purifier The benefits of having a water purifier are innumerable. Having a water purifier assures us: * To have pure and safe water, with all its minerals and nutrients positive for our health. * They improve the taste of water. Water purifiers are responsible for removing any foreign elements that can alter the taste. * We can use purified water to drink, cook or clean ourselves, avoiding possible toxins and other waste that can remain attached to our skin and, of course, inside our body. * Savings against bottled water. It is infinitely cheaper to have a home water purifier than the daily cost which is just the price of a bottle of water. * Comfort against bottled water. We avoid moving the water from one place to another, as we get directly from the hydros, also avoid having to allocate a space in our house for storing bottles. * Avoid having to go "urgently" to the market to buy bottled water. Our plants will appreciate a water free of impurities. * Extends the life of our appliances; The washing machine, the dishwasher and other elements that use water will benefit from purified water since it does not contain lime. Hydros water bottles is one of the water bottle manufacturing company, and their products are water bottles and pitchers with an inbuilt filter. Which is very useful for using in our houses. Lastly, since they remove the impurities from the water, they also end up with a good chunk of the chlorine that the supplier company has added to contribute to its purification. In addition, it is important to remember that once filtered, water does not have agents that protect against bacteria, so it should be consumed within a period of no more than two days Water purifier Water purifiers are installed directly in the potable water outlet of your residence, usually in the kitchen. The water enters the apparatus, which has a filter composed of active charcoal and colloidal silver, which will carry out the purification of water by eliminating microorganisms, bacteria, harmful agents, dirt or subs substances. They are devices, therefore, very useful in any residence or company where there is consumption of water. This is the first step for those who want to start taking care of health. Next, let's look at some of the key benefits of water purifiers, and also for other factors that should be taken into account when purchasing a water purifier. Come on! A carbon filter can cost high. If you can not afford to spend this amount of money, there is a home solution that will cost you a fifth of that price and, if you do it correctly, it will be just as effective. Let's see how it is manufactured. Hydros water bottle are manufacturing water bottles with inbuilt filter.
You will need a few materials, but they are all very cheap and can be found both in your local store and on the internet. The products that we are going to list are not exclusive, that is, you can achieve the same result, or even better, with other similar materials that you have on hand. Water filter pitchers are one of the best filter to use in house, which will removes bacteria from water. You will need to: One roll of aluminum mesh or wire A PVC cleaning cap and a PVC adapter (both with the same diameter) A tube with ventilation grille that fits the adapter A roll of asilating tape A roll of quilt filling A laundry basket (preferably with a lid) Activated carbon HOW TO PREPARE FILTER - GUIDE Make a tube with aluminum or wire mesh. Put the PVC plug on one end. Join these two elements securely with the insulating tape. Next, place the tube vertically inside the laundry basket and trim the edges so that both elements have the same height. Attach the other end of the filter to the PVC adapter with electrical tape. Remove the tube from the basket. Line both with the quilt wadding. Fold the wadding in two so that its thickness is doubled, and use it to cover the outside of the aluminum mesh. Make sure the wadding sticks out and ties everything together with the adhesive tape. Do exactly the same with the inside of the laundry basket. Place the filter tube inside the basket with the cleaning plug facing down. Once you have everything ready, fill the space between both elements with activated carbon. If you think you are using too much, the gap could be too wide. A layer of carbon of 26mm is enough. When you have finished, cover the exposed carbon with more wadding. Remember to make a hole in the lid of the basket so that the PVC adapter protrudes and you can connect it to the tube with the ventilation grid. And that's it! The only thing left to do is connect the cleaning plug to the exhaust outlet and you are ready. This will last you the same time as the commercial version of the product. Now that you have the system set up, just replace the carbon every two years and you can prevent the smell of your indoor crop from spreading. The use of activated carbon in the treatment of water has been increasing a lot since the 70's when a greater pressure of the sanitary authorities appeared on the treatment and quality of the water that is distributed to the consumers.
It is the most powerful adsorbent in the world and one of the most effective means for the removal of a wide range of industrial and municipal wastewater contaminants. Find out later on the water treatment steps and the benefits of using activated carbon. Water filter pitchers are the best one to use in House, which purifies water and makes water more tastier. REMOVAL OF ORGANIC MATTER When water passes through an activated carbon filter, the organic particles and chemicals get trapped inside it, through a process known as "adsorption." The adsorption process depends on 5 main factors: 1. Physical properties of activated carbon (surface area and pore size distribution); 2. The chemical composition of the carbon source (amount of hydrogen and oxygen); 3. Chemical composition and contaminant concentration; 4. PH and water temperature; 5. The period of time that the water is exposed to the activated carbon filter (called empty bed by contact time). Few companies like hydros water bottle are manufacturing water bottles and pitchers with an inbuilt filter. PHYSICAL PROPERTIES OF COAL AFFECTING WATER TREATMENT Pore size and distribution have the greatest impact on the effectiveness of activated carbon filtration. The best filtration occurs when the carbon pores are large enough to allow the adsorption of the contaminants. The type of contaminants that an activated carbon filter attracts will depend on the pore size of the filter, which varies based on the type of carbon used and the method of activation. Activated carbon filters tend to work best for removing organic chemicals with larger molecules. Operators should also allow for seasonal changes in water, which may mean more frequent and necessary washing of the process. |
