Generic API Test tool

1. Generic API Test tool By Moshe Sapir Almog Masika Instructor Zvika Berkovic

2. Automatic API Test Tool Concept • Enable the developer to add metadata to the modules code • Use .NET attributes to represent the metadata • The metadata should contain information which will enable automatic testing of the module • Create automatic test tool that given the module and attributes can generate tests

3. Defining Attributes: Input Output Assertion Attribute • Assertion is defined by three expressions: <P, Q, L> • If P is true before the function is run, then Q is true after the function is run, or one of the exceptions in L is thrown during execution • For double Sqrt(double x) the developer will define: • P: x > 0 • Q: ret ^ 2 = x • L = {DivisionByZero }

4. Selecting the tested method • After the attributes were defined the user can select the method to test • The selection is done using a tree view that describes the assembly structure

5. Defining test parameters • After tested method was selected the user can define the test parameters • The user is prompted for tests parameters according to the attributes defined on the tested method

6. Running the tests • After defining the test parameters, the tests are executed by the generic tool • The user can examine the test results in the tools GUI
