# Start/Stop the runtime engine

This topic includes information on how start and stop the OpenText Functional Testing for Developers runtime engine, as well as retrieve information on the runtime engine status.

While the engine is running, it always consumes at least one license. When the engine is idle for the amount of time configured in the runtime engine settings, the OpenText Functional Testing for Developers license is released and the runtime engine closes.

In this topic:

## Start the runtime engine

You can run the runtime engine to use as a stand-alone OpenText Functional Testing for Developers machine, or as part of an OpenText Functional Testing for Developers grid configuration.

For a grid configuration, run the runtime engine as a grid on the grid machine, and run it as a node on the node machines. For more details on the grid configuration, see Use a grid configuration.

Start the runtime engine in one of the following ways:

Where | Run as Stand-alone | Run as Grid or Node
--- | --- | ---
In the IDE | From the Functional Testing for Developers menu, select Start Runtime Engine. If you select Enable Functional Testing for Developers when <IDE> opens, the engine is automatically activated the next times you open your IDE. | NA
Start menu (Windows only) | Select OpenText Functional Testing for Developers Runtime. | Select one of the following: OpenText Functional Testing for Developers Runtime (Grid) OpenText Functional Testing for Developers Runtime (Grid Node)
Command line | Windows: Run `leanft start` (located in <Installdir>\bin). Linux: Run `./leanft start` (located in <Installdir>/bin). Mac: Run `./leanft start` (located in the installation directory). Note: You cannot run OpenText Functional Testing for Developers in parallel to OpenText Functional Testing or Sprinter. | Windows: Run `leanft.bat start --role=grid` or `leanft.bat start --role=node` (located in <Installdir>\bin). Linux: Run `./leanft start --role=grid` or `./leanft start --role=node` (located in <Installdir>/bin). Mac: Run `./leanft start --role=grid` or `./leanft start --role=node` (located in the installation directory). Caution: Do not run the OpenText Functional Testing for Developers runtime engine as a grid and a node on the same machine.

Note: OpenText Functional Testing for Developers nodes connect to the grid configured in their settings, regardless of whether nodes are started before or after the grid.

Therefore, when you restart an OpenText Functional Testing for Developers grid machine, you don't need to restart the nodes that were connected to it.

## Stop the runtime engine

Stop the runtime engine in one of the following ways:

From where | Deactivate the runtime engine
--- | ---
In the IDE | From the Functional Testing for Developers menu, select Stop Runtime Engine.
Task Bar / Start menu (Windows only) | Right-click the icon in the task bar and select Exit.
Command line | Windows: Run `leanft stop` (located in <Installdir>\bin). Linux: Run `./leanft stop` (located in <Installdir>/bin). Mac: Run `./leanft stop` (located in the <Installdir>). Note: To stop the grid or node runtime engine, add `--role=grid` or `--role=node` to the `stop` command.

## Retrieve runtime engine status

You can retrieve the status of the runtime engine on by running `leanft info`.

For engine status information on a grid or node machine, run `leanft info --role=grid` or `leanft info --role=node`

This information includes the OpenText Functional Testing for Developers build number, the port in use, whether the engine is running, and whether there is a valid license.

Example: (Windows)

    C:\Program Files (x86)\OpenText\Functional Testing for Developers\bin> leanft.bat info
