Method Detail

findTestNames

public static Collection<Object[]> findTestNames(String srcDir)

Scan a directory to get the names of all the whiley source files in that directory. The list of file names can be used as input parameters to a JUnit test. If the system property test.name.contains is set, then the list of files returned will be filtered. Only file names that contain the property will be returned. This makes it possible to run a subset of tests when testing interactively from the command line.

Parameters:

srcDir - The path of the directory to scan.

compile

public static wycc.util.Pair<Compile.Result,String> compile(File whileydir,
                                                            boolean verify,
                                                            String... args)
                                                     throws IOException

Run the Whiley Compiler with the given list of arguments.

Parameters:

args - --- list of command-line arguments to provide to the Whiley Compiler.

Returns:

Throws:

IOException

execWyil

public static void execWyil(File wyilDir,
                            wyfs.lang.Path.ID id)
                     throws IOException

Execute a given WyIL file using the default interpreter.

Parameters:

wyilDir - The root directory to look for the WyIL file.

id - The name of the WyIL file

Throws:

IOException

compare

public static boolean compare(String output,
                              String referenceFile)
                       throws IOException

Compare the output of executing java on the test case with a reference file. If the output differs from the reference output, then the offending line is written to the stdout and an exception is thrown.

Parameters:

output - This provides the output from executing java on the test case.

referenceFile - The full path to the reference file. This should use the appropriate separator char for the host operating system.

Throws:

IOException
