•  TDD - Test Driven Development 

               is a software development process that relies on the repetition of a very short development cycle: first the developer writes an (initially failing) automated test case   that     defines a desired improvement or new function, then produces the minimum amount of code to pass that test, and finally refactors the new code to acceptable standards.

The following sequence of steps is generally followed:                                                               1. Add a test             2. Run all tests and see if the new one fails                    

                    3.Write some code   4. Run tests                   
                    5.Refactor code        6. Repeat

• Stand-alone program -  is a computer program that does not load any external module, library function or program and that is designed to boot with the bootstrap procedure of the target processor – it runs on bare metal.

      Execute these two commands:

   D:
   cd temp

     That will get you the results you want.

SQL JOINS

• Using those new standard and earlier standard will execute in same way(Speed etc) , but this new standard is more useful , powerful  .

Git - Commands

 
•  Suppose $COMMIT_id  was the last commit id before you performed git pull. What you need to undo the last pull is         

                    git reset --hard $COMMIT_id 

•  git diff   -   Show unstaged changes between your index and working directory.                                                                                                                                          
•  git pull    -    This update whole  branches of  local  repository   .                                                                                                                                                                                  
•  The git pull  command is actually a combination of two other commands, git fetch  followed by git merge ,
it does a git fetch and then a git merge where it merges branches that have been setup to be merged in your config

                  git fetch just "downloads" the changes from the remote to your local repository. git pull downloads the changes and merges them into your
                  current branch. "In its default  mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD

• If you want to  get a file( src/main/resources/application-dev.properties) from another branch (master)  to your current working branch then,                                                                               

                  git checkout dev
                  git pull origin  dev
                  git checkout  master -- src/main/resources/application-dev.properties
