2. Interactive Management

Usually, test data is specified interactively by using the Test Data Editor (TDE), which is a part of Tessy.

You can manage (cut, copy, paste and delete) test cases in the right hand pane of Tessy’s main window.

3. File Export / Import

Export to Excel Workbooks

Tessy can export test data to Excel workbooks, i.e. to files in Microsoft Excel format (*.xls). A workbook created by Tessy is related to a single test object and contains several sheets.

Besides properties and stub function code, the workbook also contains sheets for general information, user code, and about the order of stub functions called.

Export to Text Files

Tessy can export test data to files in ASCII format (*.txt). A line specifies a test case; data is separated by tabulators.

Export to TMB Files

Tessy can export the complete test relevant information for a Tessy module (i.e. for several test objects) to a so-called TMB file. The information in the TMB file does not only include the test data, but also the interfaces of the test objects, the results of executed tests, and various settings used for testing. These settings include for instance the compiler used and its options, the floating point precision of the test evaluation, the debugger used, etc.

Import from Files

Naturally, Tessy can import information from the above mentioned file types.

Application of the File Export / Import Features

Generation of Test Data
Best suited to generate test data for a test object may be the export / import to / from Excel workbooks. The recommended method follows these steps:

• Create a single test case for your test object in question by using the Test Data Editor (TDE) of Tessy
• Export this test case to an Excel workbook
• Open the Excel workbook with Excel and add test cases by adding lines in the “Values” sheet of the Excel workbook. Test data creation may make use of the built-in functionality of Excel, e.g. to calculate expected test results.
• Import all test cases from the Excel workbook to the test object.
  

Re-use of Test Cases

Excel workbooks may be used to re-use test cases of a certain test object f1() for a similar test object f2(). Simply export the test data of f1() to an Excel workbook and then import it to f2(). If the interfaces of the two test objects do not fit, Tessy warns you and you may adapt the test data appropriately.

Configuration Management / Version Control

TMB files may be used to save a certain state of the test process. Such a TMB file may be used for version control, e.g. to save all the tests appropriate for a certain version of the software under test for later regression testing.

Transfer of Tests

TMB files may be used to transfer tests, e.g. over the internet between different geographic test locations.

Import of Test Data from Other Sources

If you already dispose over test data from other sources, e.g. test data used with proprietary systems, you might be able to convert such data into an ASCII file (or even an Excel workbook) suitable for Tessy.

4. Import from CTE

The Classification Tree Editor (CTE) accompanying Tessy can not only be used to specify tests, but also to specify test data. When transferring the test specification from CTE to Tessy, the specified test data is transferred automatically.

Test data is specified according to the following steps:

1. In the CTE: Associate interface variables with classifications

2. In the CTE: Specify values for the classes of the associated classification
