Self-testing code

Self-testing code is software that incorporates built-in tests (see test-first development). ^{[1] [2]}

Perl packages will run their self tests when they are installed using CPAN. This ensures that they run successfully in the local environment. (There is also a testing community that tests new packages and updated packages on many different platforms.)

In Java, to execute a unit test from the command line, a class can have methods like the following.

// Executing <code>main</code> runs the unit test.publicstaticvoidmain(String[]args){test();}staticvoidtest(){assertfoo==bar;}

To invoke a full system test, a class can incorporate a method call.

publicstaticvoidmain(String[]args){test();TestSuite.test();// invokes full system test}

In addition, Java has some Jupiter API libraries for self-testing code. assert can be used in various ways such as assert equals, which checks if the given variable is equal to the value given.

@Testvoidcheckplayer(){Boardboard=newBoard(10);board.addplayer(1);intcheck=board.getCurrentPlayer(1);assertEquals(1,check);}
