What is Quality Assurance QA Testing? Types & Methods

Debugging was the main testing method at the time and remained so for the next two decades. By the 1980s, development teams looked beyond isolating and fixing software bugs to testing applications in real-world settings. It set the stage for a broader view of testing, which encompassed a quality assurance process that was part of the software development life cycle. Software testing has traditionally been separated from the rest of development. It is often conducted later in the software development life cycle after the product build or execution stage.

Applying exploratory testing, skilled testers can provide valuable and auditable results. The smallest testable part of the software system is often referred to as a unit. Therefore, this testing level is aimed at examining every single unit of a software system in order to make sure that it meets the original requirements and functions as expected. Unit testing is commonly performed early in the development process by the engineers themselves, not the testing team. As soon as the primary preparations are finished, the team proceeds with dynamic testing where software is tested during execution. This whitepaper has the most focus on the dynamic testing process as a practical and most commonly used way to validate code behavior.

Ideally, this should be done after fixing issues detected during integration and unit tests. While the agile approach requires the involvement of developers in the test case writing process, they might write code simply to pass the test or subconsciously create tests with limited coverage. Making QA one of the developer’s responsibilities might result in some quality standards being neglected. For quicker turnaround in testing, automated tests can be used to supplement manual testing. Automation is the most suitable option for load tests, white box testing and other performance testing. A QA engineer typically works in the IT industry and is responsible for testing software products throughout development.

This can be used to test critical infrastructure, such as cloud servers, to see how they cope in extreme situations. This might include making sure that the software works properly on various devices and browsers, on different operating systems, and on different types of networks. If your information is vague or rigid, you might not see what you need to know in order to resolve an issue.

User Acceptance Testing

User acceptance tests and usability tests depend on the interaction between human and code, and bugs may not turn up until they’re discovered by a human in a real-world environment. But end-users can only really test the user experience of your software; without access to the underlying code, they have no way of testing for major security flaws. Instead, you show the application the workflow you want to test and the service performs those tests. Mabl can even automatically adapt to small user interface changes and alert developers to any visual changes, JavaScript errors, broken links, and increased load times. Most popular in cloud environments, security testing intends to uncover system vulnerabilities and determine how well it can protect itself from unauthorized access, hacking, any code damage, etc. While dealing with the code of application, security testing refers to the white box testing method.

  • In other words, QA takes place throughout the development process, so you don’t start up the asssembly line only to end up with a defective product, or deploy a buggy piece of software to the cloud.
  • The latter verifies that the final product meets the set requirements; the former ensures that the implementation approach will work for the user.
  • Some programs may not be “defective”, but they’re designed in such a way that they prompt a user to perform the wrong action.
  • Therefore, it is better to test every feature while the product is still being built.
  • Usability Testing – A comprehensive review of your app or software design, from usability, and user experience (UX), to the user interface (UI).

The same is the case for errors produced in the process of implementation. If a feature has a flaw in its logic, building more functionality on top of it might cause a serious damage in the long run. Therefore, it is better to test every feature while the product is still being built.

The other is “right first time,” in which any mistakes are immediately addressed. New subjects expected to affect software testing in near future are security, artificial intelligence, and big data. As a part of technological progress, testing is continually evolving to meet ever-changing business needs as it adopts new tools that allow the tester to push the boundaries of quality assurance.

Still, it’s worth noting that QA professionals need to start developing their skills so that they can add more value, as more of their daily tasks are automated. While testing and quality are inextricably linked, it’s important to understand that quality assurance testing and software testing aren’t one in the same. Part of quality assurance is finding a solution to the challenge and implementing it.

What Industries Can Benefit From Quality Assurance?

Based on the information above, here are just a few best practices to consider in QA testing. Customize tests and execute them in an environment that differs from the one used in development. Expectations for each test should be identified, and test results should be measurable. You are generally responsible for collecting and analyzing the data gathered by technicians and reporting it to a quality manager. Using this data, you will problem-solve and make recommendations for improvements.

What takes place in the next development or design cycle will be determined by the results of this phase. As a quality assurance technician, you would be responsible for testing products while they are still in the production phase to ensure they meet the standards set forth by your company. You would design testing plans, participate in resolving product issues, work as part of a team, and report on your inspection results.

Best Practices In Quality Assurance Testing

For example, when it’s too destructive or impractical to test every single product, quality control practices might include techniques like acceptance sampling. In this approach, a statistically significant sample of the product is tested to see if the number of defective items in each batch is above or below acceptable limits. Because it’s so simple, it can be applied to nearly any industry, from testing products on an assembly line to looking for bugs in a piece of software. One is “fit for purpose,” meaning the product or service meets its intended purpose.

Use case testing is applied widely in developing tests at system or acceptance levels. Use case testing checks whether the path used by the user is working as intended and makes sure the tasks can be accomplished successfully. Applying use case testing, analysts can detect shortcomings and modify the system so that it attains efficiency and Quality assurance vs. Quality control accuracy. This is an informal testing method as it’s performed without planning and documentation. Conducting tests informally and randomly without any formal, expected results, the tester improvises the steps and arbitrarily executes them.

It is part of a DevOps approach – where development and operations collaborate over the entire product life cycle. The aim is to accelerate software delivery while balancing cost, quality and risk. With this testing technique, teams don’t need to wait for the software to be built before testing starts. They can run tests much earlier in the cycle to discover defects sooner, when they are easier to fix. A type of testing that’s conducted at the ground level, unit testing is low-level testing carried out to test individual units or functions of the software under development. With unit testing, developers focus on testing during the early stages of building software to ensure that each section of your software application meets certain standards.
