Software Testing by Varun Vaddiparty

● User Interface Development● Source Code● Quality Assurance (software testing)

Need for software testing:

● Meets the requirements ● works as expected● satisfies the need of customer

Different Methods:● Static Testing● Dynamic Testing

Unit Testing

● Verify the functionality of specific section of the code.

● Usually at the function level.● To ensure that a specific function is working

as expected.

Qunit

● A Javascript unit testing framework.● It can be used to test any generic Javascript

code.● You can test your code in the browser itself.

A minimal Qunit test setup.

The contents of test.js :

Result of the test:

Asserting Results

● Essential elements of any unit tests.● You express the result expected and have the

testing framework compare them to the actual values that the functions output.

Qunit provides three assertions:● ok()● equal()● deepEqual()

ok()

● ok(truthy,[message])● most basic assertion● requires only one argument, in addition you

can send a string to show as a message

examples:ok(true,”true succeeds”);ok(1==1,”test passed”);

equal()

● equal(actual,expected,[message]);● compares your expected value with the

actual value

examples:equal(1,1,”1 equals 1, test passes”);equal(“”,0,”zero equals empty, test passes”);

deepEqual()

● deepEqual(actual,expected,[message]);● can be used just like equal, is a better choice● uses more accurate comparison operator

(===) instead of simple (==)

examples:deepEqual(0,””,”test fails, zero not equal to empty”);

expect()

● used to check whether all the assertions have been executed or not

asyncTest()

● used for asynchronous testing
