Test-Suite Template

Testing an ApCoCoA-Package

This page explains how to create a test-suite for your package. Testing is important to make sure, that your package is still working correctly, when something in ApCoCoA or the ApCoCoALib changes.

A template for a test-suite

Please respect the following points when writing a test-suite for your package:

• Create a package and name it like the corresponding package, with file ending .ts instead of the usual .cpkg
• Define a function for every test you want to realize.
• Name the functions as follows:

 Test<PackageName><MyTestName>()

• Every function realizes EXACTLY one test.
• A test can FAIL or SUCCEED. The test fails iff the test functions throws an error. To this end, use the AssertXY functions defined in assert.cpkg as much as is sensible. Note, that your test functions do not return anything.
• If you miss some AssertXY function, add it to assert.cpkg.
• You are free to add an arbitrary number of helper functions to your test-suite, just make sure that their names DO NOT start with 'Test'.

The following code shows a template for an apcocoa test package. You can find further examples of already existing test-suites in packages/apcocoa/ts of your ApCoCoA directory.

 Package $apcocoa/ts/template 

   Define Initialize()
     -- e.g. initialize variables, that you want to use for all of your tests
   EndDefine; 
 
   Define TestTemplate01() -- 1st test 

     TestRing::=QQ[x,y,z]; 

     Using TestRing Do
       $apcocoa/ts/assert.AssertTrue(x=x, "x does not equal x.");
     EndUsing; 

   EndDefine; 

   Define TestTemplate02() -- 2nd test 

     TestRing::=ZZ/(2)[x[1..5]]; 

     Using TestRing Do
       -- implementation of another test
     EndUsing; 

   EndDefine; 

   -- TestTemplate03() and so on.. 

 EndPackage;

Starting your tests

To run all the tests defined in a test-package, call

 $apcocoa/ts/aunit.RegisterTests("template");
 $apcocoa/ts/aunit.RunTests(); 

To run just a single test, call TODO.

Assert functions

The following assert functions exist by now.

• AssertTrue
• AssertEqualsExact
• AssertEqualsNumericalNumber
• AssertEqualsNumericalMatrix
• AssertEqualsNumericalPoly
• AssertEqualsListOfNumericalPoly

TestNumericalNumber

TestNumPoly

TestListOfNumPoly

TestSortedListOfNumPoly

TestNumMatrix
