Types of Software Testing

Black Box Testing- Black box testing is a software testing method where testers are not required to know coding or internal structure of the software. Black box testing method relies on testing software with various inputs and validating results against expected output.

White Box Testing-This testing is based on knowledge of the internal logic of an application’s code. Also known as Glass box Testing. Internal software and code working should be known for this type of testing. Tests are based on coverage of code statements, branches, paths, conditions.

Unit testing – Testing of individual software components or modules. Typically done by the programmer and not by testers, as it requires detailed knowledge of the internal program design and code.

Performance, Load and stress-testing in software testing?

Performance testing 

It is performed to evaluate the performance of components of a particular system in a specific situation. This type of testing generally does not give pass or fail. It is basically done to set the benchmark & standard of the application against Concurrency / Throughput, Server response time, Latency, Render response time etc. In other words, you can say it is technical & formal evaluation for responsiveness, speed, scalability and stability characteristics.

Verification And Validation

Verification:

Verification is static type of s/w testing. It means code is not executed. The product is evaluated by going through the code.

Verification is a static practice of verifying documents, design, code and program. It includes all the activities associated with producing high quality software: inspection, design analysis and specification analysis. It is a relatively objective process.

Verification will help to determine whether the software is of high quality, but it will not ensure that the system is useful. Verification is concerned with whether the system is well-engineered and error-free.
