Examples of net.sf.pipet.test.PipelineSimulator

net.sf.pipet.test.PipelineSimulator
This class helps testing PipeT modules. To use this class, define a test case. A test case consists of the following:
- a pipeline setup file (optional);
- the URI of the module which is subject to the test;
- attributes, which are arguments to the module call;
- the input data for each input pipe;
- the expected output data for each output pipe;
- the expected success status of the pipeline (true or false).
The test case is successful if:
- the output matches the expected output; and
- the success status matches the expected success status.
A test case is declared in a file. An example test case is the following:
```
 [general] #configuration = pipelines.cfg module = xml:xslt status = true [attributes] att1 = some value att2 = another value [input/xsl] file = xslt.xsl [input/input] string = <?xml version="1.0"?><xml><input/></xml> [output/output] string = <?xml version="1.0" encoding="UTF-8"?><document><element/></document> 
```
If a pipeline setup is specified (as per the configuration field, this will be the context of the module call, and the module value is interpreted within this context.

To test a custom Java module class, the module specification should generally start with class:, followed by the full class name of the module.
To instantiate a PipelineSimulator, call {@link #parseURL(URL)} with the location of a test casefile as its argument. The {@link #run} method is available to perform the test.If the test fails, an exception is thrown.

Under normal circumstances, it is not necessary to use this class directly. Instead, use {@link PipelineTest}.
