public final class SuiteLauncherDiscoveryRequestBuilder
extends Object

The SuiteLauncherDiscoveryRequestBuilder provides a light-weight DSL for generating a LauncherDiscoveryRequest specifically tailored for suite execution.

Example

 SuiteLauncherDiscoveryRequestBuilder.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(Paths.get("/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("key", "value")
   .enableImplicitConfigurationParameters(true)
   .applyConfigurationParametersFromSuite(MySuite.class)
   .applySelectorsAndFiltersFromSuite(MySuite.class)
   .build();

Method Details

request

public static SuiteLauncherDiscoveryRequestBuilder request()

Create a new SuiteLauncherDiscoveryRequestBuilder.

Returns:

a new builder

selectors

public SuiteLauncherDiscoveryRequestBuilder selectors(DiscoverySelector... selectors)

Add all supplied selectors to the request.

Parameters:

selectors - the DiscoverySelectors to add; never null

Returns:

this builder for method chaining

selectors

public SuiteLauncherDiscoveryRequestBuilder selectors(List<? extends DiscoverySelector> selectors)

Add all supplied selectors to the request.

Parameters:

selectors - the DiscoverySelectors to add; never null

Returns:

this builder for method chaining

filters

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

Add all 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

filterStandardClassNamePatterns

public SuiteLauncherDiscoveryRequestBuilder filterStandardClassNamePatterns(boolean filterStandardClassNamePatterns)

Specify whether to filter standard class name patterns.

If set to true, standard class name patterns are filtered.

Parameters:

filterStandardClassNamePatterns - true to filter standard class name patterns, false otherwise

Returns:

this builder for method chaining

configurationParameter

public SuiteLauncherDiscoveryRequestBuilder configurationParameter(String key,
 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 SuiteLauncherDiscoveryRequestBuilder configurationParameters(Map<String,String> configurationParameters)

Add all supplied configuration parameters to the request.

Parameters:

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

Returns:

this builder for method chaining

See Also:

• configurationParameter(String, String)

parentConfigurationParameters

public SuiteLauncherDiscoveryRequestBuilder parentConfigurationParameters(ConfigurationParameters parentConfigurationParameters)

Set the parent configuration parameters to use for the request.

Any explicit configuration parameters configured via configurationParameter(String, String) or configurationParameters(Map) takes precedence over the supplied configuration parameters.

Parameters:

parentConfigurationParameters - the parent instance to use for looking up configuration parameters that have not been explicitly configured; never null

Returns:

this builder for method chaining

See Also:

• configurationParameter(String, String)
• configurationParameters(Map)

enableImplicitConfigurationParameters

public SuiteLauncherDiscoveryRequestBuilder enableImplicitConfigurationParameters(boolean enabled)

Configure whether implicit configuration parameters should be considered.

By default, in addition to those parameters that are passed explicitly to this builder, configuration parameters are read from system properties and from the junit-platform.properties classpath resource. Passing false to this method, disables the latter two sources so that only explicit configuration parameters are taken into account.

Parameters:

enabled - true if implicit configuration parameters should be considered

Returns:

this builder for method chaining

See Also:

• configurationParameter(String, String)
• configurationParameters(Map)

suite

@Deprecated
public SuiteLauncherDiscoveryRequestBuilder suite(Class<?> suiteClass)

Deprecated.

as of JUnit Platform 1.11 in favor of applyConfigurationParametersFromSuite(java.lang.Class<?>) and applySelectorsAndFiltersFromSuite(java.lang.Class<?>)

Apply a suite's annotation-based configuration, selectors, and filters to this builder.

Parameters:

suiteClass - the class to apply the annotations from; never null

Returns:

this builder for method chaining

See Also:

• Suite

applyConfigurationParametersFromSuite

public SuiteLauncherDiscoveryRequestBuilder applyConfigurationParametersFromSuite(Class<?> suiteClass)

This will apply the configuration from the following annotations.

• ConfigurationParameter
• DisableParentConfigurationParameters

Parameters:

suiteClass - the class to apply the configuration annotations from; never null

Returns:

this builder for method chaining

Since:

1.11

See Also:

• Suite

applySelectorsAndFiltersFromSuite

This will apply the configuration from the following annotations.

• ExcludeClassNamePatterns
• ExcludeEngines
• ExcludePackages
• ExcludeTags
• IncludeClassNamePatterns
• IncludeEngines
• IncludePackages
• IncludeTags
• SelectClasses
• SelectClasspathResource
