'' The static procedure Test.Main() starts tests. By default it runs all testmethods in all
'' testmodules ordered by name and prints the result to the console.
''
'' The optional string Tests ca be used to define a TestSuite which can be used to choose any
'' combination of testmodule and testmethod, separated by comma.
''
'' A testmodule is a special class with the ending test. It must contain at minimum one testmethod.
''
'' A testmethod is a public sub in a testmodule whose name is not
'' "_Setup", "_Teardown", "_SetupEach" or "_TeardownEach".
''
'' A testmodule can be choosen by it's name, a testmethod by it's testmodules'
'' name followed by a dot and the name of the testmethod.
''
'' Example: Test.Main("TestWWW, TestMail.Send, TestMail.Receive")
''
'' runs all testmethods in TestWWW and the testmethods Send and Receive of the testmodule TestMail.
''
'' Public methods called "_Setup", "_Teardown", "_SetupEach" or "_TeardownEach" can be used to create a testfixture,
'' which defines a special environment for the tests.
