Steer TextStreams

To steer TextStreams, you must create TextStream Engine 3.0 TestCases.

The Standard subset contains all Modules that you need to create a TextStream TestCase. You find these Modules under Standard modules->TBox XEngines->TextStream.

For information on how to create TestSteps from Modules, see chapter "Create TestSteps from Modules".

Structure of TextStream TestCases

To create a TextStream Engine 3.0 TestCase follow the steps below:

1. Open or create a TextStream with the Module TextStream Open/Load.

   When you do so, you can simultaneously load contents from a specified external source.

2. Run your TextStream operation(s):

   • To manipulate text content in a TextStream, use the Module TextStream Block Text Manipulation.

   • To manipulate text formatted as a table in a TextStream , use the Module TextStream Table Text Manipulation.

   • To load text from an external source, either to replace or to append to the current content of a TextStream, use the Module TextStream Open/Load.

3. Close or save the TextStream with the Module TextStream Save/Close.

In this example, you perform the following actions: The TestStep TextStream Open/Load opens a TextStream called TestStream. The TestStep TextStream Table Text Manipulation verifies the content of the TextStream TestStream which is formatted as a table and uses spaces as a column separator. It verifies if the text in the first row and second column is equal to City. The second TestStep TextStream Table Text Manipulation replaces the text in the second row and second column with Boston. The TestStep TextStream Save/Close saves the TextStream TestStream to an external file encoded with Unicode UTF-8 and closes it. Steer a TextStream
