💡 Hint

Common Mistakes

Using an incorrect task name that is not registered in plugins.

Forgetting to wrap the task name in quotes.

The task name 'cwd' is commonly used to get the current working directory in Cypress tasks.

Complete the code to register a Cypress task that reads a file asynchronously.

Cypress

module.exports = (on, config) => {
  on('task', {
    readFile([1]) {
      const fs = require('fs').promises;
      return fs.readFile(path, 'utf8');
    }
  });
};

BfilePath

Cfilename

Dfile

💡 Hint

Common Mistakes

Using a parameter name different from the variable used inside the function.

Not using async/await or promises for reading files.

The parameter name 'path' matches the variable used inside the function to read the file.

Fix the error in the Cypress task that writes data to a file.

Cypress

on('task', {
  writeFile([1]) {
    const fs = require('fs');
    return fs.writeFileSync(filePath, data);
  }
});

Drag options to blanks, or click blank then click option'

AfilePath

BfilePath, data

C{filePath, data}

Ddata

💡 Hint

Common Mistakes

Passing parameters without destructuring causing undefined variables.

Using writeFileSync without proper parameters.

The function parameter should destructure an object with filePath and data to use both variables inside the function.

4fill in blank

hard

Fill both blanks to create a Cypress task that deletes a file and returns success status.

Cypress

on('task', {
  deleteFile([1]) {
    const fs = require('fs');
    try {
      fs.unlinkSync([2]);
      return true;
    } catch (err) {
      return false;
    }
  }
});

Drag options to blanks, or click blank then click option'

AfilePath

Bpath

Dfilename

💡 Hint

Common Mistakes

Using different variable names causing runtime errors.

Not handling exceptions properly.

The parameter and the argument to unlinkSync must be the same variable 'filePath' to delete the correct file.

5fill in blank

hard

Fill all three blanks to define a Cypress task that lists files in a directory and filters by extension.

Cypress

on('task', {
  listFiles([1]) {
    const fs = require('fs');
    const files = fs.readdirSync([2]);
    return files.filter(file => file.endsWith([3]));
  }
});

Drag options to blanks, or click blank then click option'

AdirPath

Bdirectory

Dext

💡 Hint

Common Mistakes

Using different variable names causing errors.

Not filtering files correctly by extension.

The parameter and argument for readdirSync should be 'dirPath', and the filter uses 'ext' to check file extensions.
