Project and Project Suite Files

Applies to TestComplete 15.69, last modified on November 13, 2024

TestComplete stores settings for each project or project suite in files of two different types: project and configuration. This is needed to maintain personal settings for each tester working with the project (if the project is used by several testers) and to separate data that are needed for test runs (common for all) from data that are used to configure and debug the project:

  • Information that is common for all testers (the number and names of project items, test item settings, the scripting language, etc.) is stored in the single project file that has the .mds extension.
  • Tester-relative settings (breakpoints information, watch expressions, etc.) are stored in a configuration file having the .tcLS extension. The name of this file coincides with the name of the project file, but the extensions differ.

    The paths and names of log files that hold testing results are also stored in the configuration file.

  • The paths, names and various other data about log files that hold testing results are stored in a single .tcLogs file. The name of this file coincides with the name of the project file, but the location and extension differ.

The configuration file typically resides in the folder of the project file. However, when the project is opened in shared mode, the configuration file can be created in another folder and even on another computer. For more information on this, see Using Test Projects in Shared Mode.

The principles applied to project files (tree-like organization and division of data into common and tester-specific properties) are also implemented for project suites. Common settings of project suites are stored in the project suite file (.pjs file) and tester-relative settings are stored in the project suite configuration files that have the .tcLS extension and the name of the project suite file. This configuration file typically resides in the folder of the project suite file. When the project suite (or its projects) are opened in shared mode, TestComplete may create the project suite configuration files in another folder.

Note that neither project, nor configuration file holds all project data. There are many other files that make up the project. For example, the project file holds references to files of project items, which, in turn, may hold references to files of their child elements, etc.

Data of the same project item may be stored both in the project and configuration files. For instance, the Tested Applications project item stores the name of a tested application in the project file, while the application path, parameters and working folder are stored in configuration files.
