Example #1
/**

 * @param dataProviderMethod the dataprovider method that gives the parameters; never {@code null}
 * @param cacheDataProviderResult determines if the dataprovider result should be cached using
 *            {@code dataProviderMethod} as key
 * @param context the execution context to use to create a {@link TestInfo} if required; never {@code null}
 *
 * @return a list of methods, each method bound to a parameter combination returned by the dataprovider
 * @throws NullPointerException if and only if one of the given arguments is {@code null}
