To test an upload file functionality with Mocha and Chai, you can follow these steps:
- Create a test file (e.g., uploadFile.test.js) where you will write your test cases.
- Install necessary dependencies (Mocha and Chai) using npm:
1
|
npm install mocha chai --save-dev |
- Import the necessary modules in your test file:
1 2 3 |
const { expect } = require('chai');
const fs = require('fs');
const uploadFile = require('./uploadFile'); // import your upload file function
|
- Write a test case to check if the file is successfully uploaded:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
describe('Upload File Test', () => {
it('should upload a file successfully', (done) => {
const filePath = './testFile.txt'; // Path to the test file
uploadFile(filePath, (err, result) => {
if (err) {
done(err);
} else {
// Check if the file was uploaded successfully
expect(result.success).to.be.true;
done();
}
});
});
});
|
- Create the upload file function in a separate file (e.g., uploadFile.js):
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
const fs = require('fs');
function uploadFile(filePath, callback) {
// Implement your file upload logic here
fs.readFile(filePath, (err, data) => {
if (err) {
callback(err, null);
} else {
// Process the file upload
// For example, you can save the file to a destination folder
// and return a success message
callback(null, { success: true, message: 'File uploaded successfully' });
}
});
}
module.exports = uploadFile;
|
- Run the tests using Mocha:
1
|
npx mocha uploadFile.test.js |
This will execute the test cases and show you the results. You can also add more test cases to cover different scenarios, such as testing for invalid file types, file size limits, etc.
