  ● User InterfaceDevelopment ● Source Code ● Quality Assurance (software testing)

  Need for softwaretesting: ● Meets the requirements ● works as expected ● satisfies the need of customer Different Methods: ● Static Testing ● Dynamic Testing
• 6.
  Unit Testing ● Verifythe functionality of specific section of the code. ● Usually at the function level. ● To ensure that a specific function is working as expected.
• 7.
  Qunit ● A Javascriptunit testing framework. ● It can be used to test any generic Javascript code. ● You can test your code in the browser itself.

  Asserting Results ● Essentialelements 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()
• 13.
  ok() ● ok(truthy,[message]) ● mostbasic 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”);
• 14.
  equal() ● equal(actual,expected,[message]); ● comparesyour expected value with the actual value examples: equal(1,1,”1 equals 1, test passes”); equal(“”,0,”zero equals empty, test passes”);
• 15.
  deepEqual() ● deepEqual(actual,expected,[message]); ● canbe 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”);
• 16.
  expect() ● used tocheck whether all the assertions have been executed or not
• 17.
  asyncTest() ● used forasynchronous testing Practical Example:
