This extensions allows you to quickly toggle between a source file and its test couterpart and vice versa. It works for any programming language and it can adapt to the way you have structured/organised the code in your project.
- Flexible and configurable filename search pattern using Regular Expression syntax
- Ability to search for source/test files in multiple (configurable) folders
Why another test switch extension?
The Visual Studio Marketplace already offers a number of extensions with similar functionality. Unfortunately I couldn't find any that would provide the flexibility I need in when working across multiple projects with multiple languages and frameworks.
For instance in a Rails project you may have an
configuration and a
lib folder containing source files and one
spec folder containing all your unit tests. In React projects it's not unusual to embed test files within the same folder of the source file. Moreover in many languages you can have multiple source/test files with the same basename representing modules/classes belonging to different namespaces, which makes it more difficult to identify the correct counterpart. Those and others are the scenarios this extension is trying to address.
How it works
Given an open file/document, this extension compiles an ordered list of candidate folders that may contain the corresponding test/source file. It then scans those folders sequentially until it finds (or not) the target document to toggle to.
- The first candidate folder is always the same folder in which the current document lives
- The last candidate folder is always the root of the project
- The presence of other folders depends on the source and test
paths extension setting
This extension provides the following configuration options:
testToggle.testNameRegExp: regular expression used to match a test filename (see
package.json for the default value)
testToggle.paths.source: list of available source paths to use when searching for source files (default:
testToggle.paths.test: list of available test paths to use when searching for test files (default:
testToggle.excludePattern: glob expression used to exclude particular paths when searching for files (default: empty string)
testToggle.typeMappings: additional file type mappings to help finding corresponding source/test files with different type/extension.
Workspace Settings examples
- Changing the
testNameRegExp to search for test files that have a suffix using uppercase (
Test) or lowercase (
- Adding source and test paths:
"testToggle.paths.source": ["app", "lib"],
"testToggle.paths.test": ["spec", "e2e"]
- Excluding paths from search:
- Using additional type mappings:
