public boolean
mayReturnZeroClassTemplateInvocationContexts(ExtensionContext extensionContext)

Overrides default org.junit.jupiter.api.extension.ClassTemplateInvocationContextProvider.mayReturnZeroClassTemplateInvocationContexts.

Signal that this provider may provide zero invocation contexts for the class template represented by the supplied context.

public Stream<ParameterizedClassInvocationContext>
provideClassTemplateInvocationContexts(ExtensionContext extensionContext)

Implements org.junit.jupiter.api.extension.ClassTemplateInvocationContextProvider.provideClassTemplateInvocationContexts.

Provide invocation contexts for the class template represented by the supplied context.

public Object
resolveParameter(ParameterContext parameterContext, ExtensionContext extensionContext)

Implements org.junit.jupiter.api.extension.ParameterResolver.resolveParameter.

Resolve an argument for the Parameter in the supplied ParameterContext for the supplied ExtensionContext.

public boolean
supportsClassTemplate(ExtensionContext extensionContext)

Implements org.junit.jupiter.api.extension.ClassTemplateInvocationContextProvider.supportsClassTemplate.

Determine if this provider supports providing invocation contexts for the class template represented by the supplied context.

public boolean
supportsParameter(ParameterContext parameterContext, ExtensionContext extensionContext)

Implements org.junit.jupiter.api.extension.ParameterResolver.supportsParameter.

Determine if this resolver supports resolution of an argument for the Parameter in the supplied ParameterContext for the supplied ExtensionContext.

Doc from org.junit.jupiter.api.extension.ClassTemplateInvocationContextProvider.mayReturnZeroClassTemplateInvocationContexts.

Signal that this provider may provide zero invocation contexts for the class template represented by the supplied context.

If this method returns false (which is the default) and the provider returns an empty stream from provideClassTemplateInvocationContexts, this will be considered an execution error. Override this method to return true to ignore the absence of invocation contexts for this provider.

public Stream<ParameterizedClassInvocationContext> provideClassTemplateInvocationContexts(ExtensionContext extensionContext)

Implements org.junit.jupiter.api.extension.ClassTemplateInvocationContextProvider.provideClassTemplateInvocationContexts.

Doc from org.junit.jupiter.api.extension.ClassTemplateInvocationContextProvider.provideClassTemplateInvocationContexts.

Provide invocation contexts for the class template represented by the supplied context.

This method is only called by the framework if supportsClassTemplate previously returned true for the same ExtensionContext; this method is allowed to return an empty Stream but not null.

The returned Stream will be properly closed by calling Stream#close(), making it safe to use a resource such as Files.lines().

public Object resolveParameter(ParameterContext parameterContext, ExtensionContext extensionContext) throws ParameterResolutionException

Implements org.junit.jupiter.api.extension.ParameterResolver.resolveParameter.

Doc from org.junit.jupiter.api.extension.ParameterResolver.resolveParameter.

Resolve an argument for the Parameter in the supplied ParameterContext for the supplied ExtensionContext.

This method is only called by the framework if supportsParameter previously returned true for the same ParameterContext and ExtensionContext.

The java.lang.reflect.Method or java.lang.reflect.Constructor in which the parameter is declared can be retrieved via ParameterContext#getDeclaringExecutable().

public boolean supportsClassTemplate(ExtensionContext extensionContext)

public boolean supportsParameter(ParameterContext parameterContext, ExtensionContext extensionContext) throws ParameterResolutionException

Implements org.junit.jupiter.api.extension.ParameterResolver.supportsParameter.

Doc from org.junit.jupiter.api.extension.ParameterResolver.supportsParameter.

Determine if this resolver supports resolution of an argument for the Parameter in the supplied ParameterContext for the supplied ExtensionContext.

The java.lang.reflect.Method or java.lang.reflect.Constructor in which the parameter is declared can be retrieved via ParameterContext#getDeclaringExecutable().
