public abstract class IntMathOps2_JML_TestData
extends junit.framework.TestCase

Supply test data for the JML and JUnit based testing of IntMathOps2.

Test data is supplied by overriding methods in this class. See the JML documentation and the comments below about how to do this.

This class is also the place to override the setUp() and tearDown() methods if your testing needs some actions to be taken before and after each test is executed.

This class is never rewritten by jmlunit.

Method Detail

overallTestSuite

public junit.framework.TestSuite overallTestSuite()
Return the overall test suite for accumulating tests; the result will hold every test that will be run. This factory method can be altered to provide filtering of test suites, as they are added to this overall test suite, based on various criteria. The test driver will first call the method addTestSuite to add a test suite formed from custom programmed test methods (named testX for some X), which you can add to this class; this initial test suite will also include a method to check that the code being tested was compiled with jmlc. After that, for each method to be tested, a test suite containing tests for that method will be added to this overall test suite, using the addTest method. Test suites added for a method will have some subtype of TestSuite and that method's name as their name. So, if you want to control the overall suite of tests for testing some method, e.g., to limit the number of tests for each method, return a special-purpose subclass of junit.framework.TestSuite in which you override the addTest method.

TestSuite
Specifications:
assignable objectState;
ensures \result != null;

emptyTestSuiteFor

public junit.framework.TestSuite emptyTestSuiteFor(String methodName)
Return an empty test suite for accumulating tests for the named method. This factory method can be altered to provide filtering or limiting of the tests for the named method, as they are added to the test suite for this method. The driver will add individual tests using the addTest method. So, if you want to filter individual tests, return a subclass of TestSuite in which you override the addTest method.

Parameters:
methodName - The method the tests in this suite are for.
See Also:
TestSuite, LimitedTestSuite
Specifications:
assignable objectState;
ensures \result != null;

vintIter

protected IntIterator vintIter(String methodName,
                               int loopsThisSurrounds)
Return a new, freshly allocated indefinite iterator that produces test data of type int for testing the method named by the String methodName in a loop that encloses loopsThisSurrounds many other loops.

Parameters:
methodName - name of the method for which this test data will be used.
loopsThisSurrounds - number of loops that the test contains inside this one.
Specifications:
requires methodName != null&&loopsThisSurrounds >= 0;
ensures \fresh(\result );
