1. Define the Methods of Software Testing in detailed
White Box Testing: Contrary to Black Box Testing this testing method uses internal paths, structures, code of the applications available for test. It needs extensive details of programming language and skills. An experienced programmer or test can conduct this
Gray Box Testing: In this strategy, a tester does not need extensive details of internal details of the program, can be done by novice professionals or called beginners.
There are mainly four testing levels used in software testing these are as follows:
Unit Testing : When it comes to check individual components or units of any applications or software are tested by tester it is called Unit Testing. The motive of this testing is to confirm that all parts and code of each unit or module is working perfectly and producing expected results. Unit testing is conducted by the programmer or developer during the course of development.

Definition of Use Case Testing
- Use case testing has nothing to do with the software quality and quality assurance of the application, its the method of how the application will be used and interaction between user and softwares.
- It is a limited testing up to module, it doesn't cover entire application, each module has its own use case testing. Every module has its own importance and separate use case testing method.
- Every Use Case has a user/actor and the application software. Its a theory how user interacts with the application. These cases are used to find the bugs and gap in softwares.
- Use case defines how the software will be used. It is the theory of step by step conducted by the actor or user. Using these steps user interacts with the application and see how the system response. It should response with expected results.
- It is the best method to find the Gap between steps, so that software should run in right flow. It should not have any gap. So it helps us to identify the gap and help developer to make application and user friendly.
- Use case plays an important role in compturing the functional requirements of the application.
- Use case testing is conducted before user acceptance, it is done by the testing professionals.
Every now and then we see Use Case in every where in our day to day life. Here we will try to understand the Use Case testing with some live examples, how we can take advantage from this. How a step by step approach helps us to develop an error free softwares.
- User puts the ATM card in the machine.
- Enter its PIN to authenticate the user identity.
- if PIN is right then allow the user to withdrawal the money from ATM machine. If PIN is wrong then ask the user to try with accurate PIN.
- User enter the right PIN and do some operations like withdraw money, change pin request, check balance and others.
- When transactions are done then sign out.
- User opens the form by clicking on the given link or opening the given URL, Actor or user may sign up or sign in as per the need, both are the important step, here user click on the login button and go to login screens.
- Enters valid credentials like user and passwords and press Login button.
- System authenticate user with given user name and password, if the credentials are ok then it allows the user to sign in or generates warning.
- Now User is logs in the website and orders some products, pay the amount and logs out.
- User visits any webpage and sees a textbox to enter email for newsletter sign up.
- User enters his email id and system validates it for proper syntax.
- If syntax is ok then it allows to sign up if wrong it asks user to enter right email id.
- User enter email id and press enter.
- System checks the entire process and accepts the email id as news letter.
