Dropwizard与Testcontainers的集成测试

testcontainers dropwizard

我试过的:

@ClassRule
public static final PostgreSQLContainer postgres = new PostgreSQLContainer();

@ClassRule
    public final DropwizardAppRule<Configuration> RULE = new DropwizardAppRule<>(
            Application.class,
            CONFIG_PATH,
            ConfigOverride.config("dataSourceFactory.url", postgres.getJdbcUrl()),
            ConfigOverride.config("dataSourceFactory.user", postgres.getUsername()),
            ConfigOverride.config("dataSourceFactory.password", postgres.getPassword())
    );

我明白了 Caused by: java.lang.IllegalStateException: Mapped port can only be obtained after the container is started

@ClassRule
    public static TestRule chain = RuleChain.outerRule(postgres = new PostgreSQLContainer())
            .around(RULE = new DropwizardAppRule<>(
                    Application.class,
                    CONFIG_PATH,
                    ConfigOverride.config("dataSourceFactory.url", postgres.getJdbcUrl()),
                    ConfigOverride.config("dataSourceFactory.user", postgres.getUsername()),
                    ConfigOverride.config("dataSourceFactory.password", postgres.getPassword())
            ));

最后,这是可行的,但据我所知,它为每个测试运行新的DropwizardAppRule,这是

@ClassRule
public static final PostgreSQLContainer postgres = new PostgreSQLContainer();

@Rule
    public final DropwizardAppRule<Configuration> RULE = new DropwizardAppRule<>(
            Application.class,
            CONFIG_PATH,
            ConfigOverride.config("dataSourceFactory.url", postgres.getJdbcUrl()),
            ConfigOverride.config("dataSourceFactory.user", postgres.getUsername()),
            ConfigOverride.config("dataSourceFactory.password", postgres.getPassword())
    );

那么,我如何链接规则,使PostgreSQLContainer首先启动,而container在创建DropwizardAppRule之前已经启动?

通过将PostgreSQLContainer初始化为singleton来实现。

    public static final PostgreSQLContainer postgres = new PostgreSQLContainer();
    static {
        postgres.start();
    }

    @ClassRule
    public final DropwizardAppRule<Configuration> RULE = new DropwizardAppRule<>(
            Application.class,
            CONFIG_PATH,
            ConfigOverride.config("dataSourceFactory.url", postgres.getJdbcUrl()),
            ConfigOverride.config("dataSourceFactory.user", postgres.getUsername()),
            ConfigOverride.config("dataSourceFactory.password", postgres.getPassword())
    );
