These days only the lazy one does not come up with some startup idea. As a result, multiple applications of the most various types pop up every day. Still, not each of them can take off and withstand a fierce rivalry. The thing is that to be a success, get well accepted, and keep end-users engaged, it is not enough to offer some brilliant idea but to bring it to life taking into account numerous aspects that influence app running and user experience. So, to make sure that your application will be highly appreciated by a target audience, it must undergo comprehensive testing. Professional software testing companies in California can provide you with an experienced QA team that will draw up an effective testing plan and execute it successfully. They will thoroughly test your software to detect bugs and vulnerabilities and reveal possible weak spots that can let prospective users down. A wide range of tests will be executed to check app functionality, stability, reliability, scalability, security, usability, compatibility, GUI, and many other things.

Roles and responsibilities of QA team members

Everyone who does not have any relation to quality assurance may get surprised by the range of QA specialist types. Most often we can hear about testers or QA engineers. Still, depending on the size and structure of a QA team and the particular needs of a company, the role of a tester can be viewed and implemented in different ways.

Below you can find the main roles of QA team members.

Manual QA Engineer or just QA Engineer

Manual QA engineers are responsible for the creation and maintenance of test cases and their manual execution. They provide inputs indicated in test cases and check whether output coincides with the expected results. They also report detected in the software defects and conduct retesting as soon as a development team informs them about the bug fixing.

Test Automation Engineer

Automated testing has been appreciated at its true value, and it is actively implemented these days. Automated tests help cut down test costs for large-scale projects in the long run, significantly speed up the process of software testing, enhance test coverage, and, consequently, improve product quality. As a result, professional test automation engineers are sought-after. Their responsibilities include the design of an automation testing plan, script creation, script maintenance, report generation, test data maintenance, and others.

Test Analyst

The role of a test analyst is rather controversial. Quite often responsibilities of a test analyst are executed by a senior QA engineer. Anyway, let’s take a closer look at it.

Test analysis is less about technical peculiarities and more about the business need awareness. Test analysts thoroughly study all available project documentation, clarify testing requirements, make a decision on what should be tested, prioritize test cases, and control test coverage. Besides, they can make active use of business data. Carefully analyzing behavior patterns of users as well as more and less commonly used app features, test analysts determine software parts of primary importance and determine potential risks.

Test Designer

If a test analyst answers a question of what to test, a test designer defines how to test it properly. A test designer is responsible for selecting an appropriate test approach, tools, and guidelines to execute the required tests in the best possible way. Quite often this role is also referred to as a test architect.

Software Development Engineer in Test (SDET)

The role of SDET was introduced at first at Microsoft. In essence, a software developer in test is a hybrid of developer and tester. This one-man-army actively collaborates with either a development team or a QA team, has full access to the source code, actively participate in debugging, easily perform responsibilities of test automation engineer, as well as design and build test automation tools that perfectly meet project requirements. It is rather difficult to find a competent SDET as this person should have a tester’s mindset and brilliant coding skills.

Test Manager

A test manager can be considered as a project manager in testing. A test manager is responsible for a test strategy design, identification of test metrics, test process planning and monitoring, assignment of responsibilities, scheduling of testing activities, test effort estimation, and many others.

Whatever California software testing company you will choose, your QA team will include specialists with different roles and responsibilities that you are well aware of now.
