Test Plan Methods

The main reason as to why a test plan and a test case are done is to allow the programmer to organize the areas that need to be tested. Testing is a tool to establish whether the system meets the original requirements. It is also a method of validating the system in such a way to check for correctness and the proper functioning of the system as a whole.

A test plan lays out the various types of testing methods that can be carried out to test the different parts of the system, to check and to make sure there are no defects and errors while running the system.

Firstly, in the testing phase, the important thing for the researcher to check is to see whether the system satisfies the needs and the goals that have been laid down by the user. This is known as Validation Testing. The next part of the validation process is known as Verification, which conforms to the specifications that have been defined in the design phase. Verification is done to check whether the system is functioning perfectly and correctly in a more formalized way. The last phase of the validation test is to check for the robustness of the system. In this area, the programmer tests to understand as to what extent the system can perform with reliability with excessive amount data held in the database within the system. A test is usually done to debug any part of the system that is not functioning to its full capability.

Following the test plan are the test cases that have been done to show the various readers and the users of the system as to the areas that have been tested for any kind of dysfunctions.

Methods for testing:

Testing is the most important phase before implementing the system. Unless the system is tested, the programmer will not know as to whether the system is working accurately and effectively. When systems are being designed, there are bound to be errors, and this is where testing comes into play.

There are two different types of testing methods that are used by programmers' to check if the system is functioning perfectly well.

White Box Testing:

White box testing is used when the internal structure of the program is to be analyzed, in order to derive the test data.

Under white box testing, there are two types of testing phases namely Unit Testing and Integration Testing.

Unit Testing:

Unit testing is understood as a method to test the correctness of a particular module of a source code. This is done during the programming stage, such that when a programmer does the coding for one module, Unit testing can be done. Testing each module of the system separately first makes it a lot easier for the integration testing to take place.

Integration Testing:

Integration testing is done after unit testing is completed. In this case sets of modules are linked together and tested as sub-systems until the system is complete. This type of testing is used to verify the functional, performance and reliability of the system. If there are no errors after all the sub-systems have been tested, then it shows that the test is successful and that the system is functioning perfectly.

Black Box Testing:

Black box testing is used to derive sets of inputs that satisfy all the functional requirements of the system.

Test Case:

Test case id

Test case name

Test case desc

Customer Id	Validate Customer Id	To verify the input for Customer Id is of number value	Validate Customer Id	The value of the Customer Id field is of number nature	The value of the Customer Id field should be of number nature	Design	High
			Validate Customer Id	The value of the Customer Id field is of number nature	The value of the Customer Id field is of character nature	Design	High
First Name & Last Name	Validate First Name and Last Name	To verify the input for First & Last Name is of character nature	Validate First Name and Last Name	The value of the First & Last Name is of character nature	The value of the First & Last Name should be of character nature	Design	High
