To become a Software Quality Analyst, it is essential to have knowledge in software testing. Software testing is responsible for ensuring that the final product meets the customer's needs and is free of errors and failures.
There are different types of software testing, such as unit testing, integration testing, system testing, acceptance testing, among others. Each type of test has a specific objective and must be performed at different stages of the software development process.
Unit tests are performed by developers and are intended to test small parts of the source code, such as functions and methods. Integration tests are responsible for testing the integration between different system modules.
System tests are performed to ensure that the system meets the functional and non-functional requirements specified by the customer. They are performed later in the software development process and can be automated to increase process efficiency.
Acceptance tests are carried out by the customer or a customer representative and are intended to verify that the final product meets their needs and expectations.
In addition to the types of tests, it is important for the Software Quality Analyst to know test techniques, such as black-box testing, white-box testing, regression testing, performance testing, among others.
Black-box testing is performed without internal knowledge of the system, testing only the input and output of the software. White-box testing, on the other hand, is performed with internal knowledge of the system, testing the source code and logic of the software.
Regression testing is performed to ensure that changes made to the software do not affect existing functionality. And performance testing is performed to verify that the software meets the performance requirements specified by the customer.
Finally, it is important that the Software Quality Analyst knows the software testing tools available on the market, such as Selenium, JUnit, TestNG, among others.
In summary, to become a Software Quality Analyst it is essential to have knowledge in software testing, including the different types of tests, test techniques and test tools available in the market.
