The following needs to be in place before a workflow can be executed:
- All input boxes need to be connected either to the workflow input or to the output of other tools.
- At least one output box from each tool needs to be connected to either a workflow output or to the input box of another tool.
- The workflow has to be Saved ().
Once these conditions are fulfilled, the Start Test Run button is enabled. Clicking this button will enable you to try running a data set through the workflow to test that it produces the expected results. If reference data has not been configured (see Configuring workflow elements), there will be a dialog asking for this as part of the test run.
