This improves the reliability of the integration tests because the communication with these dependencies are a complex part of the system and can break with a package update, a database update or a change in a queue message format. In this post, I'll show how to use Localstack and Testcontainers to emulate an AWS environment for use in integration tests.https://genezini.com/blog/p/how-to-run-scripts-on-sql-server-container-startup/Mon, 15 May 2023 06:00:00 -0300https://genezini.com/blog/p/how-to-run-scripts-on-sql-server-container-startup/<img src="https://genezini.com/blog/p/how-to-run-scripts-on-sql-server-container-startup/cover.jpg" alt="Featured image of post How to run scripts on SQL Server container startup" /> Unlike MySQL and PostgreSQL, which execute scripts in the /docker-entrypoint-initdb.d/ directory after initialization, the SQL Server container image doesn't provide a built-in mechanism for running scripts at startup. In this post, I'll show how to create a custom container image that waits for SQL Server startup and runs a pre-configured script. In addition, I'll show how to use this custom image to run SQL Server in Testcontainers.https://genezini.com/blog/p/how-to-run-disposable-databases-for-your-tests.-improve-your-integration-tests-accuracy-with-testcontainers/Mon, 09 Jan 2023 07:00:00 -0300https://genezini.com/blog/p/how-to-run-disposable-databases-for-your-tests.-improve-your-integration-tests-accuracy-with-testcontainers/<img src="https://genezini.com/blog/p/how-to-run-disposable-databases-for-your-tests.-improve-your-integration-tests-accuracy-with-testcontainers/cover.jpg" alt="Featured image of post How to run disposable databases for your tests. Improve your integration tests accuracy with Testcontainers" /> Integration tests are essential to ensure that the different components of our system work together as expected and continue to work after changes. In this post, I'll explain how to spin up disposable database containers to use in integration tests.
