Fail to launch the UFT Developer runtime engine from the IDE (Windows only)

Problem: When I try to enable UFT Developer from my IDE, I get an error message that the UFT Developer runtime engine could not be launched.

Possible cause: The wmic command used by the launcher is not recognized on your machine. This is usually because wmic is not included in your machine's path.

To verify the problem cause: 

1. From the bin folder in your UFT Developer installation folder, open a command line window.

2. Run the command: leanft.bat start

The following error message confirms that the cause of the failure is the unrecognized wmic command.

Solution:

1. Edit your system PATH environment variable and add to it the path of the wmic command.

   Tip: The path to add is usually %SystemRoot%\System32\Wbem;

2. Test this fix by typing wmic in a new command line window. This should open the wmi command line interface, which prompts with: wmic:root\cli>

3. Enable UFT Developer from your IDE.

Web is not recognized on Google Chrome

Possible cause: For UFT Developer to work in Google Chrome, the OpenText UFT Agent extension needs to be installed. If UFT Developer was installed before Google Chrome was installed, the browser extension is missing.

UFT Developer 2023 and earlier: The extension is named Micro Focus UFT Agent.

Solution:

1. Manually install the browser extension, as described in Set up Google Chrome for UFT Developer.

   After the OpenText UFT Agent extension is installed, it is displayed in the Chrome Extensions list.

2. Restart the computer.

3. Restart the UFT Developer runtime engine.

UFT Developer is not recognizing the objects in my application

Problem: UFT Developer is not recognizing the objects in my application. What should I do?

Solutions:

• If you are testing Web objects, make sure you have followed the instructions for setting up your web browsers to work with UFT Developer and that you open the web browser after the UFT Developer runtime engine is active. For details, see Set up web browsers and controls.
• Make sure your application was developed with a supported technology and version. For details, see the Support Matrix.
• If you need to test specific objects that are not supported out of the box, create Insight test objects to enable UFT Developer to access your objects via image-based recognition. For details, see Insight image-based identification (Windows only).

• To support WebAgGrid or WebUIGrid test objects, you must specifically load the AgGrid or UIGrid Web child add-in in addition to the Web add-in.

Object Identification Center (OIC): Can't add objects to an application model

Problem: The OIC recognizes the objects in my application, but I cannot save objects from the OIC to an application model.

Possible cause: The Internet browser is set to use a proxy that blocks all connections. This is unnecessarily blocking local connections as well.

Solution: Configure the Internet Options to allow local connections:

• In Local Area Network settings, select Bypass proxy server for local addresses.
• In the advance proxy settings, enter the following addresses in the Exceptions list under Do not use proxy server for addresses beginning with: localhost;127.0.0.1

ALM: "LEANFT-TEST" missing in test types

Problem: When I create a new test in my ALM test plan, I don't see LEANFT-TEST in the Type list.

Possible causes:

• The ALM patch (12.53) that supports the LeanFT test type must be installed and configured.

• After installing the 12.53, the test types may not have been manually updated. This is necessary for the new test types to appear in the Type list of existing projects.

Solution: 

1. Close ALM.

2. Install and configure the ALM 12.53 patch.

3. Log into ALM >  Site Administration and update the test types (Tools> Update Test Types). All existing active ALM projects are updated with the test type definition files that were added in the new ALM version, which include the LeanFT test type.

   For more details, see the ALM Help Center.

Cannot run test cases built with UFT Developer's MSTest 2.x templates

Test cases built using UFTd MsTest 2.x template on Visual Studio 2017 are not running. Sometimes there is no output message, and sometimes a "0 tests found" message is displayed.

Possible cause: When the MSTest 2.x nuget packages are installed, a property file is imported into the project file, adding several DLLs marked Copy To Output Directory - Copy If Newer. When a project is created using the MsTest 2.x project template, Visual Studio does not copy these DLLs to the output folder during the build.

Workaround:

1. Open the problematic MSTest 2.x project in VS2017. In a text editor, modify the .csproj file by adding an empty line at the end. Save the file, delete the empty line, and then save the file again.

2. In the message dialog box that open in Visual Studio, select Reload all.

3. Rebuild the project.

UFT Developer-BPT entities are corrupted after upgrade

Possible cause: UFT Developer-BPT entities created in a previous version of ALM can become corrupted after upgrading to a version of ALM that does not support UFT Developer, and then upgrading again to another version of ALM that does support UFT Developer.

For example, if your upgrade path was: ALM 12.01 Patch 3 > ALM 12.50 > ALM 12.53, then your entities may become corrupted.

UFT Developer-BPT entities include UFT Developer components and BPT flows or tests with UFT Developer components.

Solution: Perform a repair of the ALM project with corrupted entities, as described in the ALM Administrator Help.

Or

• Copy the UFT Developer folder containing the plugin files into IntelliJ IDEA's plugin folder.

  The UFT Developer folder containing the plugin files: <UFT Developer installation folder>\IDE\IntelliJ\plugins\LeanFT.

  IntelliJ IDEA's plugin folder: <IntelliJ's installation folder>\plugins, for example: C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2019.1.2>\plugins
