public abstract class AbstractParameterExtractionHandler
extends java.lang.Object
implements ParameterExtractionHandler

Abstract base class for parameter extraction handlers that provides common functionality and eliminates code duplication across different annotation-specific handlers. This class implements the Template Method pattern, providing a standardized flow for parameter extraction while allowing concrete implementations to define annotation-specific parsing logic.

Method Detail

extractParameters

public final java.lang.Object extractParameters(ParameterExtractionContext context)

Description copied from interface: ParameterExtractionHandler

Extracts parameters from the test method using this strategy's specific logic.

Specified by:

extractParameters in interface ParameterExtractionHandler

Parameters:

context - the parameter extraction context containing test method and annotations

Returns:

extracted parameter value (single value for simple params, Map for multiple params), or null if extraction fails

extractFromDisplayNameWithResult

protected AbstractParameterExtractionHandler.ParseResult extractFromDisplayNameWithResult(ParameterExtractionContext context)

Extracts parameter values from the test display name using regex pattern matching.

Parameters:

context - the parameter extraction context

Returns:

ParseResult containing the extracted values or failure indicator

formatParameters

protected java.lang.Object formatParameters(java.lang.Object value,
                                            ParameterExtractionContext context)

Formats the extracted parameter values into the final result format.

Parameters:

value - the extracted values

context - the parameter extraction context

Returns:

formatted parameter map with proper parameter names

createMultiParameterMap

protected java.util.Map<java.lang.String,java.lang.Object> createMultiParameterMap(java.lang.Object[] values,
                                                                                         ParameterExtractionContext context)

Creates a parameter map for multiple parameter values.

Parameters:

values - the parameter values

context - the parameter extraction context

Returns:

parameter map with named parameters

createSingleParameterMap

protected java.util.Map<java.lang.String,java.lang.Object> createSingleParameterMap(java.lang.Object value,
                                                                                          ParameterExtractionContext context)

Creates a parameter map for a single parameter value.

Parameters:

value - the parameter value

context - the parameter extraction context

Returns:

parameter map with named parameter

createGenericParameterMap

protected java.util.Map<java.lang.String,java.lang.Object> createGenericParameterMap(java.lang.Object value)

Creates a generic parameter map when method information is not available.

Parameters:

value - the parameter value or values

Returns:

generic parameter map with default parameter names

parseTypedValue

protected java.lang.Object parseTypedValue(java.lang.String value)

Parses a string value into its appropriate type with common type conversions.

Parameters:

value - the string value to parse

Returns:

the parsed typed value (Boolean, Integer, Long, Double, or String)

removeQuotes

protected java.lang.String removeQuotes(java.lang.String value)

Removes surrounding quotes from a string value.

Parameters:

value - the value to unquote

Returns:

the unquoted value

parseDisplayNameValue

protected abstract java.lang.Object parseDisplayNameValue(java.lang.String valueStr,
                                                          ParameterExtractionContext context)

Parses the value from the display name specific to this handler type.

Parameters:

valueStr - the value string from the display name

context - the parameter extraction context

Returns:

the parsed values

Throws:

java.lang.RuntimeException - if parsing fails and fallback to annotation is required

extractFromAnnotation

protected abstract java.lang.Object extractFromAnnotation(ParameterExtractionContext context)

Extracts parameter values from the annotation as a fallback.

Parameters:

context - the parameter extraction context

Returns:

the extracted values from the annotation
