'Intellisense for Jest not working in VS code

Edit: Run `npm install @types/jest` To fix

Just trying to type it() and the auto suggestion is isTag

I've tried adding a jsconfig.json

{
"compilerOptions": {
    "target": "es6"
},
"exclude": [
    "node_modules",
    "assets"
  ]
}

Thank you for anyone who has a suggestion for this!!

Add to your jsconfig.json:

{
    "typeAcquisition": {
        "include": [
            "jest"
        ]
    }
}

If this do not work try with this command:

npm install @types/jest

yarn add -D @types/jest

Just install @types/jest via this command:

npm i @types/jest --save-dev

Solution 3:^[3]

{
    "typeAcquisition": {
        "include": [
            "jest"
        ]
    }
}

for those who have no luck adding above to jsconfig.json in the root folder: try adding it to tests folder (the folder containing *.test.js files)

Non of the solution works for me. After diving into some github repos in which I found it working, I found a file called jest.config.js. Following are the configs of the file:

module.exports = {
  transform: {
    '^.+\\.ts?$': 'ts-jest',
  },
  testEnvironment: 'node',
  testRegex: './src/.*\\.(test|spec)?\\.(ts|ts)$',
  moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx', 'json', 'node'],
  roots: ['<rootDir>/src'],
};

Note: This is for ts. Change all the ts with js if you are not using typescript. After saving, Restart Vscode and it will work as expected.

This won't be for everyone but if the codebase has multiple packages in a monorepo arrangement and you use vscode as your editor, you might want to install @types/jest in the root, rather in individually.

Solution 6:^[6]

Where you call it makes a difference. Sometimes intellisense doesn't work when you are in a bad function or code block.

So if you try:

  beforeEach(() => ({
    mockedUseAccount.
  }));

Intellisense doesn't work.

If you try:

  beforeEach(() => {
    mockedUseAccount.
  });

Intellisense works fine.
