Manual testing is the technique of checking a web page, application or product by actually using it. This can be done by a human being, manually clicking through the screens, filling in the forms and generally trying to break the application.
Manual testing is important because it can reveal usability problems that are not revealed by automated or scripted testing.
Manual testing provides a complete test of the product. While automated test scripts run millions of tests in a short period of time, manual testing is often more comprehensive, as it covers all parts of the website/application/product. Manual testers look at all possible paths through the application, including error
Unit testing is a type of black-box testing in which the test code is written (or unit-tested) against the code being tested. The objective of writing unit tests is to catch bugs or regressions as early as possible in the development process by systematically testing individual units of code, instead of later testing whole applications.
Unit tests are often written by developers before the code is written, thus providing some degree of test documentation and ensuring that all parts of a module are working properly.
Unit tests can be run in an automated fashion, allowing for fast feedback on code changes and continuous integration.
A smoke test is a quick initial test of a program or module to verify that it does not have obvious bugs. It can be considered a subset of an integration test. It is often the first test in the software testing process, and is usually performed by the programmer or tester who wrote the code. Smoke tests are often done on an ongoing basis, even after an initial release.
The term comes from the idea of emitting smoke from a ship’s stack to determine if there are any problems with its machinery. If no smoke appeared, there was no problem with the machinery. The same principle applies to smoke tests. If everything works correctly, there should be no need for further testing.
Functional Testing is one of the most important areas of testing, especially for larger applications. It is also very difficult to test functional behavior. A functional test requires an understanding of the application’s business functionality, the system environment, and how users are expected to use the application. Functional tests can be done manually or automated with various tools.
Testing possibilities include:
Testing based on requirements specification. Tests are created based on requirements specification. By basing the testing on requirements specifications, you ensure that user requirements have been met by the development team. The main disadvantage of this approach is that there may be some requirements that were not documented and thus do not get tested. This process does not provide any coverage of non-functional requirements such as performance and security.
Testing based on user stories in scrum methodology . In this case, you base tests on user stories and scenarios that describe how a feature is used in practice for a particular user role. The advantage of this approach is that it provides coverage of non-functional requirements such as load and performance tests.

Integration testing is a software testing process that joins together different software modules and tests them as a group. Integration tests verify the interfaces between components and detect problems caused by interaction between these components.
The purpose of integration testing is to find bugs that reside in the interfaces and interaction points between software components. Integration tests verify that a group of functionally independent components work together correctly as a system.
Integration testing builds on black box (also called functional) testing techniques, but differs in that it also verifies the communication pathways between components or subsystems.
Regression Testing is the process of ensuring that new changes to an application or on-going development have not broken any existing functionality. It is an ongoing activity on any significant development project where the application is subject to constant change. Regression testing will identify if changes made to one part of the system have had an unintended effect on other areas of the system.
Regression Testing is a type of white box testing . Regression testing can be performed manually or by writing automated regression test scripts . Automated tests are preferred as they offer greater accuracy and consistency, and quicker execution time.
It is used to perform any action which is 100% automation testing. Keyword testing is scripted at the backend. Sometimes manual testing is performed by us if there is such kind of work which doesn’t involve scripting.
