Hands-On Auto DevOps with GitLab CI - Integration and Functional Testing

The video tutorial covers Section 4 on application quality and monitoring, focusing on enhancing DevOps pipelines. It discusses integration and functional testing, code quality analysis, and application monitoring using Prometheus. The tutorial provides a detailed example of using services in GitLab CI for testing a Nodejs application with a Postgres database. It explains configuring environment variables, using Docker containers, and setting up aliases for services. The video concludes with a successful integration test and a preview of the next topic on code quality analysis.

What is the primary goal of enhancing a DevOps pipeline?

• To improve application quality

• To reduce server costs

• To eliminate the need for testing

• To increase the number of developers

What is the main difference between unit tests and integration tests?

• Integration tests evaluate the application as a whole

• Integration tests focus on individual components

• Unit tests are more comprehensive

• Unit tests require a database

Why is it important to use a separate database instance for testing?

• To use different database software

• To save on costs

• To increase test speed

• To avoid polluting the production database

What is the role of a service in GitLab CI?

• To replace the main container

• To provide additional functionality to the main container

• To store code

• To manage user access

How does GitLab CI ensure that a service is ready for use?

• By checking the service's version

• By verifying the service's configuration file

• By waiting for a specific port to be active

• By running a test script

What is the benefit of using an alias for a service in GitLab CI?

• To reduce memory usage

• To increase processing speed

• To simplify service identification

• To enable multiple instances

What does the integration test in the example demonstrate?

• The Node.js application is faster than other applications

• The Node.js application does not require testing

• The Node.js application can connect to a Postgres database

• The Node.js application can run without a database
