Instrumented version of Jest for Storybook Interactions
Storybook integration for Jest, instrumented for use with the Interactions addon.
This is likely an issue with newer package managers.
The @storybook/jest
package provides some type augmentations so that expect
has extended matchers coming from Testing Library. The way it works, is that @storybook/jest
depends on @testing-library/jest-dom
, a package that depends on @types/testing-library__jest-dom
. That @types package should be hoisted in your project in order for your types to fully work. As a result, you should have a node_modules/@types/testing-library__jest-dom
directory. If you don't, then the types won't exist and that's why you're having issues.
For instance, if you have a yarn project, hoisting happens automatically. However if you're using pnpm, @types
are not hoisted automatically, you will have to add a .npmrc
file with the following setting:
// .npmrc
public-hoist-pattern[]=@types*
Otherwise, installing @types/testing-library__jest-dom
as a direct dependency should have the same effect and fix your issue.
If you are still experiencing issues after making these changes, it's very likely that your tsconfig.json
file contains specific type overrides, which means that it will ignore automatic types, for instance:
{
"compilerOptions": {
"types": [
"node",
"mocha",
]
}
}
In that case, make sure to add testing-library__jest-dom
to the types
array:
{
"compilerOptions": {
"types": [
"node",
"mocha",
"testing-library__jest-dom"
]
}
}
