Xpediter/Code Coverage 3.1

August 1, 2016
Quantify the Thoroughness of Your Testing Efforts

Xpediter/Code Coverage is an advanced analysis tool that clearly and easily identifies how much of an application has or has not been executed. Code Coverage helps identify the percent of code executed for single or multiple programs, for one test or for multiple tests run over time, and from a high-level management view down to a single line of code.

Code Coverage works in conjunction with Compuware’s mainframe test and debugging tools Xpediter/CICS and Xpediter/TSO and Xpediter/IMS. As you perform your testing, Code Coverage keeps track of what parts of your code have been exercised and what parts have not. The results generated by Code Coverage can be displayed, analyzed, and output using Xpediter/DevEnterprise and Compuware Program Analyzer. You can also output detailed reports directly from Code Coverage on the mainframe.

What’s New
Release Notes Standardization

The Software and Hardware Requirements section of the release notes has been standardized across all Compuware Mainframe products and their Distributed components. Please note that any versions of third-party software that are no longer supported by their vendors under standard published contracts have been removed from the Software and Hardware Requirements section and placed in the Discontinued Support section of the release notes. However, any third-party software that was supported when this Compuware product went GA will continue to be supported until this product release has reached its End of Support date. No functionality has been removed from the product.

Batch Program Test Data Optimization

When used in conjunction with Xpediter/TSO, Code Coverage will now provide a list of records, identified either by sequence number or index key, that are associated with first-time code execution. This provides a way for you to eliminate redundant test cases; i.e. “optimizing” your test data.

Note: Only COBOL programs using QSAM, VSAM, or IMS access methods are supported.

Low-Priority Code Exclusion

The previous release of Xpediter/Code Coverage provided the ability to identify “high-risk” code: new code that hadn’t yet been run in a production environment. It might be an entire program or added or changed code implemented during a maintenance task. This high-risk code is weighted more heavily when compiling the Relative Risk Metric for a program indicating how well it’s been tested. Xpediter/Code Coverage reporting, both on the mainframe and in the GUIs of Xpediter/DevEnterprise and Compuware Program Analyzer, highlights untested new code very clearly.

To complement that capability, Xpediter/Code Coverage users have been requesting some type of “low-risk” identification. Low-risk code could be commonly used utility modules or error routines that haven’t changed and have been reliable for years. Low-risk code might also be code that would be very difficult to test, such as time-outs on responses from other sources outside of the application or other conditions that can’t easily be created with test data.

The new Low-Priority Code Exclusion feature in Xpediter/Code Coverage gives you the ability to identify “low-risk” code and exclude it from reporting. Unexecuted low-risk code does not affect the Relative Risk Metric, having no effect on the reporting of tested and non-tested code counts and percentages.

This essentially adds a third level of code definition to Xpediter/Code Coverage, supplementing the existing high-risk and normal-risk levels found in earlier versions of Code Coverage.

Specification of low-risk code follows the existing methods already used for identifying high-risk code: code stamps or beginning/ending values used within the code, as well as “filters” to isolate and categorize the code accordingly.

Expanded Line Filters

Code Coverage’s Individual Line filters had previously been limited to eight characters in length. While this was adequate for “code stamps” placed in the areas reserved for comments by the compiler, Compuware learned that these filters were sometimes being used to describe data element names to be treated as high-risk code, and eight characters are not sufficient in many cases to uniquely identify those data elements. This enhancement expands the available Individual Line filter length to 50 characters.

Xpediter/Code Coverage’s Individual Line filtering capabilities are also being enhanced to provide “match on word” specification. With “match on word” specifically requested, a filter of “all” will return only the matches for the standalone word “all”. Without “match on word” specified, a filter of “all” will return not only the word “all”, but additional words in which the character string “all” is embedded, such as “allow”, “allocate”, and “mall”.

Sharing of Filters Among Users

Prior to this release, Code Coverage mainframe filters used for identifying “high-risk” code couldn’t be shared between ISPF users. The filters were saved within an ISPF profile for individual reuse, but there was no way to make them available to other Code Coverage users.

With this enhancement, Code Coverage provides a facility that allows filters to be shared among multiple users.

CICS System Flow Reporting

Release 3.1, in conjunction with Xpediter/CICS, provides the ability to print out CICS System Flow information from the standard mainframe Code Coverage reports menu. System name, test ID, and user ID can be used as filters to the report generation process.

This System Flow information can be particularly useful for sites that have inherited unfamiliar, often complex, applications, either from outsourcing or through mergers, and are eager to gain some initial understanding of what’s going on inside them. In such situations, the calling sequence determined at runtime can provide valuable insights.

Xpediter/Code Coverage Maintenance Support

How to Use a PDX File to Search a Compuware Documentation Set

Compuware creates a PDX file for each release of every mainframe product. The file is available in ZIP format on FrontLine, Compuware’s customer support website, along with this README and a folder containing two data files. By pre-cataloging the content of the product’s PDFs, the PDX file allows you to quickly search across the entire documentation set without having to search each PDF individually.

To use the PDX file for a Compuware product:

1. Go to FrontLine ( and navigate to the Documentation page for the desired product.

2. Download all of the PDF files for that product to the same local directory. (The Compuware Installer PDF is only cataloged in the Enterprise Common Components PDX file.)

3. Download the ZIP containing the product’s index file.

4. Extract the contents of the ZIP, sending it to the same directory as the PDF files. Be sure to select “All files/folders in archive” and “Use folder names.”

5. Double click the product’s PDX file (< product >Index.pdx). A Search dialog box will appear with the index pre-selected.

6. Enter a word or phrase to search for. To optimize your search, select one or more qualifiers such as “Whole words only,” then click Search.

Your search results will appear almost instantly, grouped by document. Each document with results can be expanded to show a list of matches, with each match including a brief sample of the context in which it occurred. Every match is hyperlinked to the specific page in the PDF where it was found, enabling you to quickly locate the information you’re looking for.
