Showcasing different examples with testcontainers
This repository functions as a collection of examples using testcontainers. Tests are written with Kotest.
This repository is not meant to be run as an actual application
SSHServerContainer: A testcontainer based off linuxserver/openssh-server
This container is used in conjunction with SSHKeyGenerator, which will generate an RSA keypair in a temp directory.
As showcased in SftpSessionFactoryIntegrationTest, the keypair is generated, then the SFTP container is created, with the public key path provided as a parameter before starting the container.
The test then showcases how to build an SFTP session factory and make a real SFTP call into the running container.
CockroachDbContainer: A testcontainer based off the official Cockroach image. Notice that it does not automatically start - this is to allow the test utilizing the testcontainer to control when to start it.
I have provided two different examples showcasing testcontainers with Cockroach: a JPA-centered approach, and a more manual PGSimpleDataSource approach.
The CockroachDbContainer is utilized in both integration tests, but with the JPA test, it uses Spring to configure the data source and other beans. The other integration test constructs the data source manually with the container details.
As showcased in BookRepositoryIntegrationTest, I utilize a base specification, JpaDatabaseSpec, which handles configuring the application context and beans for the repository test. It then demonstrates saving a simple entity and querying for it to prove the testcontainer Cockroach database container.
As showcased in PGSimpleDataSourceIntegrationTest, the data source is constructed with the details of the container, and verifies the data source connection is valid.
