ac_check_junit

AC_CHECK_JUNIT tests the availability of the Junit testing framework, and set some variables for conditional compilation of the test suite by automake.

If available, JUNIT is set to a command launching the text based user interface of Junit, @JAVA_JUNIT@ is set to $JAVA_JUNIT and @TESTS_JUNIT@ is set to $TESTS_JUNIT, otherwise they are set to empty values.

You can use these variables in your Makefile.am file like this :

 # Some of the following classes are built only if junit is available
 JAVA_JUNIT  = Class1Test.java Class2Test.java AllJunitTests.java

 noinst_JAVA = Example1.java Example2.java @JAVA_JUNIT@

 EXTRA_JAVA  = $(JAVA_JUNIT)

 TESTS_JUNIT = AllJunitTests

 TESTS       = StandaloneTest1 StandaloneTest2 @TESTS_JUNIT@

 EXTRA_TESTS = $(TESTS_JUNIT)

 AllJunitTests :
    echo "#! /bin/sh" > $@
    echo "exec @JUNIT@ my.package.name.AllJunitTests" >> $@
    chmod +x $@

AC_CACHE_VAL(ac_cv_prog_JUNIT,[

else

AC_SUBST(JAVA_JUNIT)
AC_SUBST(TESTS_JUNIT)])
