Abstract

Methods and apparatus, including computer program products, for handling parameters in a test script for testing a computer program application. A method includes executing a test script for testing a function of a computer program, the test script including a command invoking the function, the command having arguments, the command arguments in the test script including a set of test input parameters for the function; determining the required input parameters for the function; and detecting an error if there is a mismatch between the required input parameters and the test input parameters.,

Claims

1. A method for handling parameters in a test script, comprising:

executing a test script for testing a function of a computer program, the test script including a command invoking the function, the command having arguments, the command arguments in the test script including a set of test input parameters for the function;

determining the required input parameters for the function; and

detecting an error if there is a mismatch between the required input parameters and the test input parameters.

2. The method of claim 1, further comprising:

determining the required input parameters for the function by obtaining meta-data describing the function as it exists in a particular installation of the computer program.

3. The method of claim 2, further comprising:

obtaining information identifying the particular installation;

obtaining information identifying the actual version of the computer program as installed in the particular installation; and

selecting the test script from multiple test script versions based on the actual version of the computer program.

4. The method of claim 1, further comprising:

terminating the test script and reporting the error if the test input parameters include more than the required input parameters.

5. The method of claim 1, further comprising:

terminating the test script and reporting the error if the test input parameters include more than the required input parameters and a strict mode of operation is in effect.

6. The method of claim 1, further comprising:

terminating the test script and reporting the error if the test input parameters do not include all the required input parameters and no default values have been established for the parameters missing from the test input parameters.

7. The method of claim 1, further comprising:

obtaining information identifying a target system;

obtaining information identifying the actual version of the computer program as installed on the target system; and

selecting the test script from multiple test script versions based on the actual version of the computer program.

8. The method of claim 1, further comprising:

receiving a test configuration, the test configuration having associated with it the test script and one or more data containers;

where each data container defines a set of parameters and one or more sets of variants, each set of variants specifying a value for each of the parameters in the set of parameters, and where each data container is reusable with multiple test configurations; and

where the test configuration further has a set of test parameter variants, each of the test parameter variants being a set of values for respective test input parameters, and where the test parameter variants include one or more references for obtaining data values from one or more of the associated data containers.

9. A method for executing test scripts, comprising:

receiving a set of test records defining variant parameter values for test parameters;

receiving a first and a second test script for testing a function of a computer program, the test scripts having distinct first and second sets of import parameters, respectively;

executing the first and second test scripts against first and second versions of the computer program, respectively, using the same set of test records to provide import parameter values.

10. The method of claim 9, further comprising:

obtaining information identifying a first and a second target system;

obtaining information identifying the actual first and second versions of the computer program as installed on the target systems; and

selecting the first and second test scripts from multiple test script versions based on the actual first and second versions of the computer program.

11. A computer program product, tangibly embodied in an information carrier, for storing instructions for handling parameters in a test script, the computer program product being operable to cause data processing apparatus to:

execute a test script for testing a function of a computer program, the test script including a command invoking the function, the command having arguments, the command arguments in the test script including a set of test input parameters for the function;

determine the required input parameters for the function; and

detect an error if there is a mismatch between the required input parameters and the test input parameters.

12. The computer program product of claim 11, further comprising instructions to:

determine the required input parameters for the function by obtaining meta-data describing the function as it exists in a particular installation of the computer program.

13. The computer program product of claim 12, further comprising instructions to:

obtain information identifying a target system;

obtain information identifying the actual version of the computer program as installed on the target system; and

select the test script from multiple test script versions based on the actual version of the computer program.

14. The computer program product of claim 11, further comprising instructions to:

terminate the test script and reporting the error if the test input parameters include more than the required input parameters.

15. The computer program product of claim 11, further comprising instructions to:

terminate the test script and reporting the error if the test input parameters include more than the required input parameters and a strict mode of operation is in effect.

16. The computer program product of claim 11, further comprising instructions to:

terminate the test script and reporting the error if the test input parameters do not include all the required input parameters and no default values have been established for the parameters missing from the test input parameters.

17. The computer program product of claim 11, further comprising instructions to:

obtain information identifying a target system;

obtain information identifying the actual version of the computer program as installed on the target system; and

select the test script from multiple test script versions based on the actual version of the computer program.

18. The computer program product of claim 11, further comprising instructions to:

receive a test configuration, the test configuration having associated with it the test script and one or more data containers;

where each data container defines a set of parameters and one or more sets of variants, each set of variants specifying a value for each of the parameters in the set of parameters, and where each data container is reusable with multiple test configurations; and

where the test configuration further has a set of test parameter variants, each of the test parameter variants being a set of values for respective test input parameters, and where the test parameter variants include one or more references for obtaining data values from one or more of the associated data containers.

19. A computer program product, tangibly embodied in an information carrier, for storing instructions for executing test script, the computer program product being operable to cause data processing apparatus to:

receive a set of test records defining variant parameter values for test parameters;

receive a first and a second test script for testing a function of a computer program, the test scripts having distinct first and second sets of import parameters, respectively;

execute the first and second test scripts against first and second versions of the computer program, respectively, using the same set of test records to provide import parameter values.

20. The computer program product of claim 19, further comprising instructions to:

obtain information identifying a first and a second target system;

obtain information identifying the actual first and second versions of the computer program as installed on the target systems; and

select the first and second test scripts from multiple test script versions based on the actual first and second versions of the computer program.
