testAT2JavaConversion

public void testAT2JavaConversion()

Test the conversion function Symbiosis.ambientTalkToJava for various kinds of input.

testJava2ATConversion

public void testJava2ATConversion()

Test the conversion function Symbiosis.javaToAmbientTalk for various kinds of input.

testWorkingInstanceInvocation

public void testWorkingInstanceInvocation()

Invokes the two instance methods gettertest and settertest on atTestObject. Also performs a selection of the field 'xtest' Also invokes the method 'identitytest' to see whether AT->Java conversion does proper unwrapping

testWorkingClassInvocation

public void testWorkingClassInvocation()

Invokes the class method 'prefix' and performs a selection and assignment of the static 'ytest' field

testFaultyArity

public void testFaultyArity()

Invokes the method 'gettertest' with one argument instead of zero.

testIllegalArgs

public void testIllegalArgs()

Invokes the method 'settertest' with a double (fraction) instead of an int (number)

testIllegalAssignment

public void testIllegalAssignment()

Tries to assign to a final public field

testVarArgInvocation

public void testVarArgInvocation()

Test whether variable arguments work

testOverloadedInvWithOneMatch

public void testOverloadedInvWithOneMatch()

Tests whether overloaded methods can be properly invoked if they can be resolved to one method using the actual arguments.

testOverloadedInvWithMultipleMatches

public void testOverloadedInvWithMultipleMatches()

Invokes an overloaded method where the symbiosis cannot disambiguate automatically.

testOverloadedInvWithNoMatch

public void testOverloadedInvWithNoMatch()

Invokes an overloaded method that does not match the specified argument type

testNonExistentMethod

public void testNonExistentMethod()

Invokes a method that is not defined in the class.

testFirstClassFields

public void testFirstClassFields()

Tests first-class field access for both instances and classes

testFirstClassMethods

public void testFirstClassMethods()

Tests first-class method access for both instances and classes

testCasting

public void testCasting()

Tests casting to manually resolve overloaded method invocations Selecting a method from a Java object results in a JavaClosure instance. Such a Java closure understands the message 'cast', which allows the programmer to manually restrict the wrapped JavaMethods to specific type signatures. In this case, the two choices overloadedmatch2(Object) overloadedmatch2(SymbiosisTest) are manually restricted such that only the second one remains applicable

testSymbiontParents

public void testSymbiontParents()

Tests whether the parent pointers of the AT symbionts refer to the proper objects.

testSymbiontInstanceAdditions

public void testSymbiontInstanceAdditions()

Tests whether new per-instance methods and fields can be added to a wrapped Java object.

testSymbiontDuplicates

public void testSymbiontDuplicates()

Tests whether no duplicate methods or fields can be added to a wrapped Java object.

testSymbiontClassAdditions

public void testSymbiontClassAdditions()

Tests whether new per-class methods and fields can be added to a wrapped Java class. Also tests whether existing instances can make use of these newly added methods

testCloning

public void testCloning()

Tests cloning behaviour for both wrapped class instances and classes.

testWorkingInstanceCreation

public void testWorkingInstanceCreation()

Tests the invocation of new on a wrapped Java Class. Instantiates the Java class via the default init implementation.

testNonInstantiatableCreation

public void testNonInstantiatableCreation()

Tests whether classes with private constructors terminate cleanly.

testIllegalArgsInstanceCreation

public void testIllegalArgsInstanceCreation()

Tests whether incorrect arguments passed to constructor terminate cleanly.

testOverloadedInstanceCreation

public void testOverloadedInstanceCreation()

Tests whether overloaded constructors which cannot be resolved terminates cleanly.

testExceptionInInstanceCreation

public void testExceptionInInstanceCreation()

Tests an instance creation that raises an exception

testCreationViaJavaObject

public void testCreationViaJavaObject()

Tests the invocation of new on a wrapped Java Object, rather than on a Java Class.

testCustomInstanceCreation

public void testCustomInstanceCreation()

Tests the invocation of new on a wrapped Java Class. Instantiates the Java class via a custom new implementation. BEWARE: this test should be the last for testing symbiotic instance creation as it MODIFIES the test fixture (the JavaClass wrapper object)! Ths is because the JavaClass wrapper is pooled and reused throughout subsequent tests.

testJLobbyPackageLoading

public void testJLobbyPackageLoading()
                              throws InterpreterException

Tests whether jlobby.java results in a new JavaPackage. Tests whether jlobby.java.lang results in a new JavaPackage. Tests whether jlobby.java.lang.Object results in the proper loading of that class

Throws:

InterpreterException

testJLobbyExplicitClassLoading

public void testJLobbyExplicitClassLoading()
                                    throws InterpreterException

Tests whether lowercase classes can be loaded via the class method of a JavaPackage.

Throws:

InterpreterException

public void testJLobbyNonexistentClassLoading()
                                       throws InterpreterException

Tests whether access to a nonexistent class gives rise to a selector not found exception.

Throws:

InterpreterException

testJLobbyExplicitPackageLoading

Throws:

InterpreterException

testBugfixOverloadedConstructor

public void testBugfixOverloadedConstructor()
                                     throws InterpreterException

BUGFIX TEST: jlobby.java.lang.StringBuffer.new(10) failed to discriminate between constructors StringBuffer(String) and StringBuffer(int), reason was that anything native was convertible to NATText and also to String. Fixed by reimplementing asNativeText in NATNil to throw a type exception as usual.
