source-map-fixtures
Simple test fixtures backed by inline source maps and source map files. Can be used to test code that needs to resolve or apply source maps.
Requirements
The fixtures should work in Node.js 0.10 and up. Generating fixtures requires some ES2015 features, Node.js 5 or up is recommended.
Installation
npm install --save-dev source-map-fixtures
Source maps will only change between major versions. New fixtures or other features may be added in minor releases.
Available fixtures
branching
See src/branching.js. Exports a run(value) function which returns true if
value === 42, else returns undefined.
istanbul-ignore
Like branching, but the if condition is prefaced with a /* istanbul ignore if */
comment.
If the exported run(value) is called with a value other than 42 the
statement body won't execute, but this does not result in missing coverage. It
would in the branching fixture.
istanbul-ignore-fn
Like istanbul-ignore, but the if condition guards a function call. The
function declaration is prefaced with /* istanbul ignore next */. The function
won't execute unless the exported run(value) is called with 42.
simple
See src/simple.js. Exports a run() function which returns 42.
throws
See src/throws.js. Exports a run() function which returns throws an error.
bundle
See src/bundle.js. Bundled version of the above fixtures, exports
branching(value), istanbulIgnore(), simple() etc.
Available source map types
inline
The source map is included inside the fixture source.
map-file
The source map is provided as a separate file, referenced by the fixture source.
none
No source map is provided.
API
const fixtures = Use fixtures.inline(name), fixtures.mapFile(name) and fixtures.none(name),
where name is one of branching, simple, etc. This returns a fixture
object:
const fixture = fixture.name
Provides the name of the fixture.
fixture.type
Provides the source map type of the fixture (inline, map-file, none).
fixture.file
Provides the full path to the fixture file.
fixture.sourceFile
Provides the full path to the fixture's source file.
fixture.require()
Requires the fixture file (returns it as a module).
fixture.contentSync()
Synchronously reads the fixture file's content from disk.
fixture.sourceContentSync()
Synchronously reads the fixture's source's content from disk.
