assertResultsAreValid

public static void assertResultsAreValid(TypecheckResult testResult)

TODO: REDO COMMENT Compares the result of the compiler against an array of Strings.

In a checker, we treat a more specific error message as subsumed by a general one. For example, "new.array.type.invalid" is subsumed by "type.invalid". This is not the case in the test framework; the exact error key is expected.

ensureDirectoryExists

public static void ensureDirectoryExists(File path)

testBooleanProperty

public static boolean testBooleanProperty(String propName)

testBooleanProperty

public static boolean testBooleanProperty(String propName,
                                          boolean defaultValue)

getShouldEmitDebugInfo
