java.lang.Object

io.micronaut.testresources.testcontainers.AbstractTestContainersProvider<T>

io.micronaut.testresources.r2dbc.core.AbstractR2DBCTestResourceProvider<T>

Type Parameters:

T - the container type

All Implemented Interfaces:

io.micronaut.core.order.Ordered, TestResourcesResolver

Direct Known Subclasses:

R2DBCMariaDBTestResourceProvider, R2DBCMSSQLTestResourceProvider, R2DBCMySQLTestResourceProvider, R2DBCOracleXETestResourceProvider, R2DBCPostgreSQLTestResourceProvider

public abstract class AbstractR2DBCTestResourceProvider<T extends org.testcontainers.containers.GenericContainer<? extends T>>
extends AbstractTestContainersProvider<T>

Base class for R2DBC test resources. Unlike JDBC test resources, this resolver is capable of reusing an existing JDBC test resources and expose it via R2DBC: this can be useful for Flyway database migrations which work over JDBC for example. For this to work, a datasource of the same name must exist, in which case it would be resolved first. If no such datasource exists, then a new container will be created.

Method Detail

getRequiredPropertyEntries

public java.util.List<java.lang.String> getRequiredPropertyEntries()

getRequiredProperties

public java.util.List<java.lang.String> getRequiredProperties(java.lang.String expression)

Description copied from interface: TestResourcesResolver

Returns the list of properties which should be read before resolving an expression: this can be used if the resolver itself needs some configuration properties.

Parameters:

expression - the expression which needs to be resolved.

Returns:

the list of configuration properties this resolver requires

getResolvableProperties

public java.util.List<java.lang.String> getResolvableProperties(java.util.Map<java.lang.String,java.util.Collection<java.lang.String>> propertyEntries,
                                                                java.util.Map<java.lang.String,java.lang.Object> testResourcesConfig)

Description copied from interface: TestResourcesResolver

Returns the list of properties that this resolver is able to support. The property entries map is a map which keys are the property entries retrieved from calling TestResourcesResolver.getRequiredPropertyEntries() and values are those property entries resolved.

Parameters:

propertyEntries - the property entries

testResourcesConfig - the test resources configuration

Returns:

the list of properties

shouldAnswer

protected boolean shouldAnswer(java.lang.String propertyName,
                               java.util.Map<java.lang.String,java.lang.Object> requestedProperties,
                               java.util.Map<java.lang.String,java.lang.Object> testResourcesConfiguration)

Description copied from class: AbstractTestContainersProvider

Determines if this resolver can resolve the requested property. It is used in order to make sure that a "Postgres" resolver wouldn't provide a value if the requested container type is for MySQL, for example.

Overrides:

shouldAnswer in class AbstractTestContainersProvider<T extends org.testcontainers.containers.GenericContainer<? extends T>>

Parameters:

propertyName - the property to resolve

requestedProperties - the resolved properties

testResourcesConfiguration - the test resources configuration

Returns:

if this resolver should answer

resolveWithoutContainer

protected java.util.Optional<java.lang.String> resolveWithoutContainer(java.lang.String propertyName,
                                                                       java.util.Map<java.lang.String,java.lang.Object> properties,
                                                                       java.util.Map<java.lang.String,java.lang.Object> testResourcesConfiguration)

Description copied from class: AbstractTestContainersProvider

Lets a resolver provide a value for the requested property without triggering the creation of a test container. This can be used in case a resolver wants to check existing containers first.

Overrides:

resolveWithoutContainer in class AbstractTestContainersProvider<T extends org.testcontainers.containers.GenericContainer<? extends T>>

Parameters:

propertyName - the name of the property to resolve

properties - the properties used to resolve

testResourcesConfiguration - the test resources configuration

Returns:

a resolved property

resolveProperty

protected final java.util.Optional<java.lang.String> resolveProperty(java.lang.String expression,
                                                                     T container)

Specified by:

resolveProperty in class AbstractTestContainersProvider<T extends org.testcontainers.containers.GenericContainer<? extends T>>

extractOptions

protected abstract java.util.Optional<io.r2dbc.spi.ConnectionFactoryOptions> extractOptions(org.testcontainers.containers.GenericContainer<?> container)
