Q:

How to derive test scenarios and use cases? What are the contents and format?

Answer

 Test scenarios are derived from requirement documents. We follow each and every functionality (called business rules) mentioned in the requirement document. One functionality can have multiple business rules. For example, let us say in there is one requirement called “Login”. This “Login” may have various scenarios. For example, one scenario is, enter the right User ID and wrong password. The system should display an error message. Another scenario would be to enter wrong User ID and right Password. The system should display an error message. The third scenario could be to enter the right User Name and right Password. The system should allow the user to get into the system. This is how the test cases are derived from the requirement documents or from the Use Cases.

Q:

Which is a reserved word in the java programming language?

A) Variable B) Identifier
C) Keyword D) Main
 
Answer & Explanation Answer: C) Keyword

Explanation:

Reserved words are words that cannot be used as object or variable names in a Java program because they're already used by the syntax of the Java programming language.

Java reserved words are keywords that are reserved by Java functions or other uses that cannot be used as identifiers (e.g., variable names, function names, class names).

If a reserved word was used as a variable you would get an error or unexpected result.

 

Examples : Int, Long, Abstract, Class, Break, Catch, Case, Public, Static, Void,...

Q:

You are a tester. Now How will you choose which defect to remove in 1000000 defects?

Answer

First thing testers are not responsible for fixing the bug they are only responsible for debugging the bug and prioritizing those bugs. These bugs are now reported in bug report template with the severity and priority of the bug. Tester assigns severity level to the defects depending upon their impact on other parts of application. Every bug has its severity and priority values assign by tester. If a defect does not allow you to go ahead and test the product, it is critical one so it has to be fixed as soon as possible. We have 5 levels as:


 


Critical


High


Medium


Low


Cosmetic
