<div id="mw-content-text" class="mw-body-content mw-content-ltr" lang="en" dir="ltr"><div class="mw-content-ltr mw-parser-output" lang="en" dir="ltr">Self-testing code is software that incorporates built-in tests (see <a href="Test-first_development" class="mw-redirect" title="Test-first development">test-first development</a>).<a href="#cite_note-1">[1]</a><a href="#cite_note-2">[2]</a>

<a href="Perl" title="Perl">Perl</a> packages will run their self tests when they are installed using <a href="CPAN" title="CPAN">CPAN</a>. 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 <a href="Java_(programming)" class="mw-redirect" title="Java (programming)">Java</a>, to execute a <a href="Unit_test" class="mw-redirect" title="Unit test">unit test</a> from the <a href="Command_line" class="mw-redirect" title="Command line">command line</a>, a <a href="Class_(computer_science)" class="mw-redirect" title="Class (computer science)">class</a> can have methods like the following.

<div class="mw-highlight mw-highlight-lang-java mw-content-ltr" dir="ltr"><pre>// Executing <code>main</code> runs the unit test.

public static void main(String[] args) {

test();

}

static void test() {

assert foo == bar;

}

</pre></div>

To invoke a full <a href="System_test" class="mw-redirect" title="System test">system test</a>, a class can incorporate a method call.

<div class="mw-highlight mw-highlight-lang-java mw-content-ltr" dir="ltr"><pre>public static void main(String[] args) {

test();

TestSuite.test(); // invokes full system test

}

</pre></div>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.<div class="mw-highlight mw-highlight-lang-java mw-content-ltr" dir="ltr"><pre>@Test

void checkplayer() {

Board board = new Board(10);

board.addplayer(1);

int check = board.getCurrentPlayer(1);

assertEquals(1, check);

}
