Method Detail

setUp

protected void setUp()
              throws Exception

The setup method run before each test.

Overrides:

setUp in class DrJavaTestCase

Throws:

Exception - This convention is mandated by JUnit.TestCase, the superclass of this class.

tester

private void tester(Pair<String,Object>[] cases)
             throws InterpreterException

Asserts that the results of interpreting the first of each Pair is equal to the second.

Parameters:

cases - an array of Pairs

Throws:

InterpreterException

interpret

private Object interpret(String s)
                  throws InterpreterException

Throws:

InterpreterException

testConstants

public void testConstants()
                   throws InterpreterException

Make sure interpreting simple constants works. Note that strings and characters are quoted.

Throws:

InterpreterException

testBooleanOps

public void testBooleanOps()
                    throws InterpreterException

Test simple operations with Booleans

Throws:

InterpreterException

testShortCircuit

public void testShortCircuit()
                      throws InterpreterException

Tests short circuiting

Throws:

InterpreterException

testIntegerOps

public void testIntegerOps()
                    throws InterpreterException

Tests integer operations.

Throws:

InterpreterException

testDoubleOps

public void testDoubleOps()
                   throws InterpreterException

Test double operations.

Throws:

InterpreterException

testStringOps

public void testStringOps()
                   throws InterpreterException

Test string operations

Throws:

InterpreterException

testCharacterOps

public void testCharacterOps()
                      throws InterpreterException

Test character operations.

Throws:

InterpreterException

testSemicolon

public void testSemicolon()
                   throws InterpreterException

Tests that String and character declarations do not return a result, while the variables themselves return a quoted result.

Throws:

InterpreterException

testNullInstanceOf

public void testNullInstanceOf()
                        throws InterpreterException

Tests that null can be used in instanceof expressions.

Throws:

InterpreterException

testVariableDefinition

public void testVariableDefinition()
                            throws InterpreterException

Tests simple variable definitions which broke the initial implementation of variable redefinition (tested by testVariableRedefinition).

Throws:

InterpreterException

testVariableDefaultValues

public void testVariableDefaultValues()
                               throws InterpreterException

Tests that variables are assigned default values.

Throws:

InterpreterException

testVariableRedefinition

public void testVariableRedefinition()
                              throws InterpreterException

Tests that variable declarations with errors will not allow the interpreter to not define the variable. This will get rid of annoying "Error: Redefinition of 'variable'" messages after fixing the error. Note that if the error occurs during the evaluation of the right hand side then the variable is defined. This is for two reasons: The compiler would have accepted this variable declaration so that no more variables could have been defined with the same name afterwards, and we don't know how to make sure the evaluation doesn't return errors without actually evaluating which may have side-effects.

Throws:

InterpreterException

testIncompatibleAssignment

public void testIncompatibleAssignment()
                                throws InterpreterException

Ensure that the interpreter rejects assignments where the right type is not a subclass of the left type.

Throws:

InterpreterException

testTypeCheckerExtension

public void testTypeCheckerExtension()

Test the operation of the TypeCheckerExtension by performing the operations ((false) ? 2/0 : 1) and ((false) ? 2%0 : 1), which should not throw Exceptions in the Java interpreter.

testEvaluationVisitorExtensionNO_RESULT

public void testEvaluationVisitorExtensionNO_RESULT()

Test the operation of the EvaluationVisitorExtension by performing a computation with no results (interpreter should return NO_RESULT and not null)

testInitializeArrays

public void testInitializeArrays()
                          throws InterpreterException

Test that arrays initializers are accepted.

Throws:

InterpreterException

testArrayCloning

public void testArrayCloning()
                      throws InterpreterException

Test that array cloning works.

Throws:

InterpreterException

testDeclareVoidMethod

public void testDeclareVoidMethod()

Tests that declaring a void method in the Interactions Pane won't cause a bad type exception. Tests bug #915906 "Methods in Interactions no longer work".

testUserDefinedVoidMethod

public void testUserDefinedVoidMethod()
                               throws InterpreterException

Tests that a call to user-defined void method returns NO_RESULT, instead of null. This test does not pass, it is currently broken.

Throws:

InterpreterException

testThrowNull

public void testThrowNull()
                   throws InterpreterException

Test throwing null, for bug 3008828.

Throws:

InterpreterException
