This ESLint plugin helps ensure that React components have the necessary testID attribute, which is crucial for effective testing of React applications.
npm install eslint-plugin-react-require-testidshell
yarn add eslint-plugin-react-require-testid --dev
`
Usage
After installation, you need to configure ESLint to use this rule. Here's an example configuration:
`javascript
{
"plugins": ["react-require-testid"],
"rules": {
"react-require-testid/testid-missing": ["error", {
"disableDefaultComponents": [],
"enableComponents": []
}]
}
}
`
In this configuration:
- disableDefaultComponents allows you to specify default components to exclude from the rule check.
- enableComponents allows you to specify additional components to include in the rule check.
###### Rule Logic
- The rule iterates through JSX opening elements in your code.
- It filters out default React components based on the configuration.
- It merges the filtered default components with any additional components specified.
- For each JSX opening element, it checks if the component is allowed and if it has a data-testid attribute.
- If the component is allowed but lacks a data-testid attribute, a linting error is reported.
###### Example
Consider the following JSX code snippet:
With the ESLint rule configured, it will raise a linting error if MyCustomComponent is included in the allowed components list but does not have a data-testid` attribute.
