Behavior when an input is verified for the first time.

Behavior depends on if an EmptyFiles can be found matching the current extension.

• If an EmptyFiles can be found matching the current extension, then the tool will be launched to compare the input to that empty file.
• If no EmptyFiles can be found no tool will be launched.

Behavior when a difference is detected between the input and an existing current verified file.

If no tool is running for the comparison of the current verification (per test), a new tool instance will be launched.

If a tool is running for the comparison of the current verification (per test), and a new verification fails, the following logic will be applied:

The bundled DiffEngineViewer is the exception: it queues every failing pair into one window, so none of the four rows describes it.

This allows, in most cases, for no manual closing of the tool to be required.

By default a maximum of 5 tool instances will be launched. This prevents a change that breaks many tests from causing too much load on a machine.

This value can be changed using an environment variable or by explicitly specifying the value by code. When both are used, the value set in code wins; the environment variable is the ambient default for a run that sets nothing.

The count includes DiffEngineViewer, but only when a viewer has to be started. Handing a pair to one already on screen opens no window and so spends nothing.

Setting the DiffEngine_MaxInstances environment variable to the number of instances to launch.

This value can also be set using the DiffEngineTray options dialog.

DiffRunner.MaxInstancesToLaunch(10);

snippet source | anchor

By default, when a diff is opened, the temp file is on the left and the target file is on the right.

This value can be changed by setting the DiffEngine_TargetOnLeft environment variable to true.

This value can also be set using the DiffEngineTray options dialog.

If a tool is running for the comparison of the current verification (per test), and a new verification passes, the following logic will be applied:

This allows, in most cases, for no manual closing of the tool to be required.

Resharper has a feature Check for orphaned processes spawned by test runner.

By default, ReSharper maintains a list of all processes that are launched by the executed tests. If some of theses processes do not exit after the test execution is over, ReSharper will suggest you to terminate the process. If your setup requires some processes started by the tests to continue running, you can clear this checkbox to avoid unnecessary notifications.

Since this project launches diff tools, it will trigger this feature and a dialog will show:

All unit tests are finished, but child processes spawned by the test runner process are still running. Terminate child process?

As such this feature needs to be disabled:

Add the following to [Solution].sln.DotSettings.

<s:String x:Key="/Default/Housekeeping/UnitTestingMru/UnitTestRunner/SpawnedProcessesResponse/@EntryValue">DoNothing</s:String>

ReSharper | Options | Tools | Unit Testing | Test Runner

File | Settings | Manage Layers | This computer | Edit Layer | Build, Execution, Deployment | Unit Testing | Test Runner

Tools location is automatically detected. If a tool installed in a custom location, it can be manually configured using an environment variable, that points to the executable. The environment variable format is DiffEngine_{ToolName}.

Non-MDI tools are preferred since it allows DiffEngineTray to track and close diffs.

DiffTools.UseOrder(DiffTool.VisualStudioCode);

• Command line reference
• When a change is accepted by editing in the diff view, VS Code saves the file using files.eol (crlf on Windows by default), which can change its line endings. Consumers that require a specific line ending (for example Verify, which rejects a verified file containing crlf) can break. Install the EditorConfig extension to honor end_of_line from .editorconfig on save, or set "files.eol": "\n".
