Class DefaultDataProviderMethodResolver

java.lang.Object

com.tngtech.java.junit.dataprovider.internal.DefaultDataProviderMethodResolver

All Implemented Interfaces:

DataProviderMethodResolver

public class DefaultDataProviderMethodResolver
extends java.lang.Object
implements DataProviderMethodResolver

Default implementation to resolve the dataprovider method for a test method using UseDataProvider annotation.

It is being tried to resolve the dataprovider method using various strategies. The locations of the dataprovider can optionally specified using UseDataProvider.location(). If no specific location is specified, test class itself is used (= where @UseDataProvider annotation is used). If multiple locations are specified, each is searched for an appropriate dataprovider.

The name of the dataprovider method can be explicitly set via UseDataProvider.value() or derived by convention. The first found dataprovider method will be used. Here are the applied strategies:

• Explicitly configured name using UseDataProvider.value(). (no fallback if dataprovider could not be found)
• @DataProvider annotated method which name equals the test method name
• @DataProvider annotated method whereby prefix is replaced by one out of the following:

  prefix	replacement
  test	dataProvider
  test	data

• @DataProvider annotated method whereby additional prefix "dataProvider" or "data" is given. Also the first letter of the original test method name is uppercased, e.g. shouldReturnTwoForOnePlusOne corresponds to dataProviderShouldReturnTwoForOnePlusOne.

resolve

public java.util.List<org.junit.runners.model.FrameworkMethod> resolve(org.junit.runners.model.FrameworkMethod testMethod,
                                                                       UseDataProvider useDataProvider)

Returns the dataprovider methods that belongs to the given test method or an empty List if no such dataprovider method could be found.

Look at the classes java doc for detailed description of the applied strategies.

Specified by:

resolve in interface DataProviderMethodResolver

Parameters:

testMethod - test method that uses a dataprovider

useDataProvider - UseDataProvider annoation on the given test method

Returns:

the resolved dataprovider method or an empty List if dataprovider could not be found (never null)
