@API(status=STABLE,
     since="1.0")
public final class LauncherDiscoveryRequestBuilder
extends java.lang.Object

The LauncherDiscoveryRequestBuilder provides a light-weight DSL for generating a LauncherDiscoveryRequest.

Example

 import static org.junit.platform.engine.discovery.DiscoverySelectors.*;
 import static org.junit.platform.engine.discovery.ClassNameFilter.*;
 import static org.junit.platform.launcher.EngineFilter.*;
 import static org.junit.platform.launcher.TagFilter.*;

 // ...

   LauncherDiscoveryRequestBuilder.request()
     .selectors(
        selectPackage("org.example.user"),
        selectClass("org.example.payment.PaymentTests"),
        selectClass(ShippingTests.class),
        selectMethod("org.example.order.OrderTests#test1"),
        selectMethod("org.example.order.OrderTests#test2()"),
        selectMethod("org.example.order.OrderTests#test3(java.lang.String)"),
        selectMethod("org.example.order.OrderTests", "test4"),
        selectMethod(OrderTests.class, "test5"),
        selectMethod(OrderTests.class, testMethod),
        selectClasspathRoots(Collections.singleton(new File("/my/local/path1"))),
        selectUniqueId("unique-id-1"),
        selectUniqueId("unique-id-2")
     )
     .filters(
        includeEngines("junit-jupiter", "spek"),
        // excludeEngines("junit-vintage"),
        includeTags("fast"),
        // excludeTags("slow"),
        includeClassNamePatterns(".*Test[s]?")
        // includeClassNamePatterns("org\.example\.tests.*")
     )
     .configurationParameter("key1", "value1")
     .configurationParameters(configParameterMap)
     .build();

LauncherDiscoveryRequestBuilder

public LauncherDiscoveryRequestBuilder()

Method Detail

request

public static LauncherDiscoveryRequestBuilder request()

Create a new LauncherDiscoveryRequestBuilder.

Returns:

a new builder

selectors

public LauncherDiscoveryRequestBuilder selectors(DiscoverySelector... selectors)

Add all of the supplied selectors to the request.

Parameters:

selectors - the DiscoverySelectors to add; never null

Returns:

this builder for method chaining

selectors

public LauncherDiscoveryRequestBuilder selectors(java.util.List<? extends DiscoverySelector> selectors)

Add all of the supplied selectors to the request.

Parameters:

selectors - the DiscoverySelectors to add; never null

Returns:

this builder for method chaining

filters

public LauncherDiscoveryRequestBuilder filters(Filter<?>... filters)

Add all of the supplied filters to the request.

The filters are combined using AND semantics, i.e. all of them have to include a resource for it to end up in the test plan.

Warning: be cautious when registering multiple competing include EngineFilters or multiple competing exclude EngineFilters for the same discovery request since doing so will likely lead to undesirable results (i.e., zero engines being active).

Parameters:

filters - the Filters to add; never null

Returns:

this builder for method chaining

configurationParameter

public LauncherDiscoveryRequestBuilder configurationParameter(java.lang.String key,
                                                              java.lang.String value)

Add the supplied configuration parameter to the request.

Parameters:

key - the configuration parameter key under which to store the value; never null or blank

value - the value to store

Returns:

this builder for method chaining

configurationParameters

public LauncherDiscoveryRequestBuilder configurationParameters(java.util.Map<java.lang.String,java.lang.String> configurationParameters)

Add all of the supplied configuration parameters to the request.

Parameters:

configurationParameters - the map of configuration parameters to add; never null

Returns:

this builder for method chaining

configurationParameter(String, String)

build

public LauncherDiscoveryRequest build()

Build the LauncherDiscoveryRequest that has been configured via this builder.
