Version 2.0 (R2007b) SystemTest™ Software Release Notes

Version 2.0 (R2007b) SystemTest Software

This table summarizes what's new in Version 2.0 (R2007b):

New features and changes introduced in this version are:

• Distributed Testing

• Randomized Test Vectors

• Grouped Test Vector Support in the Test Results Viewer

• Run SystemTest Tests from the MATLAB Command Line

• Platforms No Longer Supported

• Invalid Characters in Element Names

Distributed Testing

You can now distribute the SystemTest software tests across multiple computers or processors for faster performance. You must have a license for the Parallel Computing Toolbox™ software to use this feature.

You can set up a test and then distribute the test iterations as tasks, which are performed by different workers. No changes to the test setup are required. This can speed up the total time the test takes to execute.

Randomized Test Vectors

The SystemTest software now provides an easy way to generate randomized test vector values for your test. Probability distribution functions can be used to set up test vectors, which is useful for performing Monte Carlo analyses.

If you have the Statistics Toolbox™ software, the SystemTest software integrates with it to provide use of some of its probability distribution functions, such as Exponential, Gamma, Lognormal, T, and Weibull. If you don't have the Statistics Toolbox software, you have access to MATLAB probability distribution functions such as Normal (Gaussian) and Uniform.

Grouped Test Vector Support in the Test Results Viewer

The Test Results Viewer now lets you use grouped test vectors in plot configurations.

You can also show grouped test vectors as dependent variables in scatter plots. If a dependent variable is a grouped test vector, you can now explore the relationship it has with the other vectors in the group.

Run SystemTest Tests from the MATLAB Command Line

You can now run tests that you set up in the SystemTest software from the MATLAB command line. This is useful for running multiple tests as a batch or calling a test file as part of an M-file.

Platforms No Longer Supported

The following platforms are no longer supported for use with the SystemTest software:

• Solaris™ 64

• PowerPC^® Mac^®

Note that since these platforms are not supported, you cannot have any worker machines in a distributed testing cluster that use these platforms.

Invalid Characters in Element Names

The following characters are now considered invalid to include within element names:

• '

• <

• >

You cannot use these three characters in element names. If you create a new test element with one or more of these characters in the element name, then the SystemTest software throws an error dialog and the element name is reset to the default value, which is the name of the element type.

Compatibility Considerations

If you try to load an existing test with an invalid element name (containing one or more of the three characters listed above), the SystemTest software displays an error dialog indicating that the element name is invalid. The test will load successfully, but the element with an invalid name is reset to use the default name for the element.

If this occurs, simply rename the element to a name that does not contain any of the invalid characters. You rename an element by double-clicking its name in the Test Browser.
