Organize tests with proper resource lifecycle management to ensure reliability and maintainability. Create test resources once in `before` hooks rather than in individual tests, and clean them up in corresponding `after` hooks. For shared resources, use unique identifiers (e.g., timestamps) to prevent conflicts between test runs.
Organize tests with proper resource lifecycle management to ensure reliability and maintainability. Create test resources once in before hooks rather than in individual tests, and clean them up in corresponding after hooks. For shared resources, use unique identifiers (e.g., timestamps) to prevent conflicts between test runs.
Group related tests into logical suites using descriptive describe blocks to improve organization and simplify cleanup:
describe('S3 object operations', function() {
var s3;
var bucketName = 'test-bucket-' + Date.now(); // Unique identifier
before(function(done) {
s3 = new AWS.S3();
// Create resources once
s3.createBucket({Bucket: bucketName}).promise()
.then(function() {
return s3.waitFor('bucketExists', {Bucket: bucketName}).promise();
})
.then(function() {
done();
});
});
after(function(done) {
// Clean up resources in corresponding after hook
s3.deleteBucket({Bucket: bucketName}).promise()
.then(function() {
done();
});
});
// Individual tests that use the shared bucket
it('should upload an object', function() {
// Test implementation
});
it('should download an object', function() {
// Test implementation
});
});
This approach prevents resource exhaustion, improves test execution speed, and reduces flakiness from race conditions or rate limiting. Separating environment-specific tests (browser vs. Node.js) into different folders further improves organization and prevents execution in incorrect environments.
