Typescript
If your editor does not recognise the custom jest-extended
matchers, add a global.d.ts
file to your project with:
import 'jest-extended';
caution
When using ts-jest >= 25.5.0
Since the breaking changes in 25.5.0
you may also need to update your tsconfig.json
to include the new global.d.ts
file in the files
property like so:
{
"compilerOptions": {
...
},
...
"files": ["global.d.ts"]
}
Also note that when adding this for the first time this affects which files are compiled by the TypeScript compiler and you might need to add the include
property as well. See the TypeScript docs for more details.
If the above import syntax does not work, replace it with the following:
/// <reference types="jest-extended" />
