The test coverage using statement testing is the measure of the source code or statements executed by test scripts. In bottom-up integration, testing starts from lower-level modules to higher-level modules up in the hierarchy. qa automation engineer training Similar to top-down integration, the higher-level modules might not have got created by the time lower-level modules are tested. These drivers are dummy modules that simulate the functionality of higher-level modules.
Testers execute predetermined test cases to identify functionality issues rather than internal implementation problems. Generally speaking, automated testing is faster, more efficient, and more reliable than manual testing, but it requires expertise in the programming language and software tools used. It is one of the types of testing in which an application is evaluated for its functioning across the world independent of its geographical location or cultural environment. It is the subset of regression testing, which is carried out when there is some minor fix in the application in a new build.
It is the third level of testing, in which the complete integrated application is tested as a whole. It aims at determining if the application conforms to its business requirements. It is the same as black-box testing which requires validating the specifications of the application under test without the knowledge of the internal architecture of the system.
- Functional testing is another broad term used in the testing world to refer to testing activities where what is being tested is the actual functionality of the system.
- Big Data Testing is verifying and validating the quality of large and complex data sets used in applications or systems.
- Metamorphic testing (MT) is a property-based software testing technique, which can be an effective approach for addressing the test oracle problem and test case generation problem.
- Smoke testing for login will check whether the login screen is accessible and if the users can log in.

Functional vs non-functional testing
Manual testing is done in person, by clicking through the application or interacting with the software and APIs with the appropriate tooling. This is very expensive since it requires someone to setup an environment and execute the tests themselves, and it can be prone to human error as the tester might make typos or omit steps in the test script. Agile testing includes continuous testing throughout the development cycle, with frequent testing and feedback loops to ensure software meets customer requirements. It often includes testing the application to identify any issues or bugs and taking corrective actions before the release. This requires no working knowledge of an application’s internal functions or processes.
It is the same as component testing which includes validating an individual module of an application. It includes validating the application with a newer version of the other platform or software. The experienced-based testing techniques are completely based on the experience or intuition of the tester. In this technique, we test the application by picking the test data lying in the boundary values of the equivalence classes. More importantly, it assures the quality of your product, allowing you to stand equally and even excel beyond your competitors. It involves retesting software components to ensure that the changes have not caused unintended or side effects and that the software continues functioning as intended.
In this process, unit tests are written first, by the software engineers (often with pair programming in the extreme programming methodology). Unit tests are maintained along with the rest of the software source code and generally integrated into the build process (with inherently interactive tests being relegated to a partially manual build acceptance process). These types of tests are usually written by developers as they work on code (white-box style), to ensure that the specific function is working as expected.
