Unit testing is a type of automated testing. You can write unit testing without using TDD or BDD, just by writing the tests after the production code. TDD is a software development methodology, in which the developer writes code in very short cycles, always starting with a failing test.

System integration testing is done mainly to test the interface requirements of a system. Whereas user acceptance testing is done to verify the system functionality as a whole by an end-user. Appropriate test cases have to be written for both the testing.

Difference between Assert and Verify in selenium In case of verify, tests will continue to run until the last test is executed even if assert conditions are not met. Verify or Soft Asserts will report the errors at the end of the test.

JUnit is a framework that helps with writing and running your unit tests. Mockito (or any other mocking tool) is a framework that you specifically use to efficiently write certain kind of tests. ... In order to do that, you very often have to create "test doubles" that you provide to an object of your "class under test".

Test-Driven development is a process of developing and running automated test before actual development of the application. Hence, TDD sometimes also called as Test First Development.

Test Coverage. For those who aren't familiar with these terms, code coverage is a measure of code that is executed throughout testing, while test coverage is a measure of how much of the feature being tested is actually covered by tests*. ...

Selenium is a tool that remote-controls a browser. You can use it to simulate a user interacting with a web site. JUnit is a framework for writing Java unit tests. ... JUnit will run the tests for you and report which tests passed and which failed.

Unit testing allows the programmer to refactor code or upgrade system libraries at a later date and make sure the module still works correctly. Unit tests detect changes that may break a design contract. They help with maintaining and changing the code. ... Unit testing verifies the accuracy of the each unit.

In QTP, data-driven testing is easier as it has built-in global and local tables whereas in Selenium we need to rely on programming language capabilities. In Selenium, we can execute multiple tests in parallel whereas in QTP we can execute only one test at a time.

Static testing is about the prevention of defects whereas Dynamic testing is about finding and fixing the defects. Static testing does the verification process while Dynamic testing does the validation process. Static testing is performed before compilation whereas Dynamic testing is performed after compilation.

Whereas QA is proactive, QC is reactive. ... Testing is a subset of QC. It is the process of executing a system in order to detect bugs in the product so that they get fixed. Testing is an integral part of QC as it helps demonstrate that the product runs the way it is expected and designed for.

In waterfall testing, testing is a separate phase. In agile testing, testing is performed alongside the development. In waterfall testing, testing is carried out only after the completion of development. In agile testing, development team and testing team work together.

KEY DIFFERENCE Static testing checks the code, requirement documents, and design documents to find errors whereas Dynamic testing checks the functional behavior of software system, memory/CPU usage and overall performance of the system.

API testing is basically black box testing which is simply concerned with the final output of the system under test. 1. Unit testing aims to verify whether the module delivers the required functionality. The development team monitors unit testing activity and makes necessary changes wherever required.

FDD stands for Frequency Division Duplex, and TDD stands for Time Division Duplex. ... TDD systems use a single frequency band for both transmit and receive. A system shares the same band and assigns alternative time slots for transmit and receive operations.

According to Test Automation in wikipedia a tool is dependent on the environment whereas a framework provides the structure for running the tool. ... We call both of these "frameworks" but they both need to be run using a testing framework like NUnit or JUnit. So I feel they should be called tools because of this.
