Difference between functional testing & integression testing

 1. First of all let's talk simply meaning of testing:

      Testing simply means that to check functionality or module work properly in software,hardware,etc.

 2. Now let's talk functional testing:

      Functional testing meaning that to check only functionality work is properly or not.

      let's understand with an example:

      (i)Tester check login functionality

      It means that we check the login button means if login successfully and go to the dashboard page by click on the login button after what happened not to worries about (only when checking functional testing😄😄) 

      (ii) To check the feedback button functionality:

      It means that when clicking on the feedback button open the feedback page. Not worry and test to enter a valid data field in every column, feedback sent successfully bu click on submit button. 

      (this called integration testing  we will study in the next topic in this post)

3. Now let's talk about Integration testing:

    Integration testing means to check each and everything open this particular page and then after entering data validation show or not.

    For example:

    to check register button functionality with integration testing:

    1. when clicking on the register button open the register page

    2. after open register to check every field 

        for example, let's take some scenarios for register

        (i) without enter any field and click on the save button then should be shown a validation message:

             "Please enter all mandatory field"

        (ii)  enter less/greater than 10 digits of mobile no. then must be shown validation message:

              "Please enter 10 digits of your mobile no. or invalid mobile no."

        (iii) in name field not allow in special cahracter 

        (iv) In mobile number not allowed alphabetic or only open digit keypad
