#
|
|
# Purpose
|
|
#
|
|
# Generates the test suite code given inputs of the test suite directory that
|
|
# contain the test suites, and the test suite file names for the test code and
|
|
# test data.
|
|
#
|
|
# Usage: generate_code.pl <suite dir> <code file> <data file> [main code file]
|
|
#
|
|
# Structure of files
|
|
#
|
|
# - main code file - 'main_test.function'
|
|
# Template file that contains the main() function for the test suite,
|
|
# test dispatch code as well as support functions. It contains the
|
|
# following symbols which are substituted by this script during
|
|
# processing:
|
|
# TESTCASE_FILENAME
|
|
# TESTCODE_FILENAME
|
|
# SUITE_PRE_DEP
|
|
# MAPPING_CODE
|
|
# FUNCTION CODE
|
|
# SUITE_POST_DEP
|
|
# DEP_CHECK_CODE
|
|
# DISPATCH_FUNCTION
|
|
# !LINE_NO!
|
|
#
|
|
# - common helper code file - 'helpers.function'
|
|
# Common helper functions
|
|
#
|
|
# - test suite code file - file name in the form 'test_suite_xxx.function'
|
|
# Code file that contains the actual test cases. The file contains a
|
|
# series of code sequences delimited by the following:
|
|
# BEGIN_HEADER / END_HEADER - list of headers files
|
|
# BEGIN_SUITE_HELPERS / END_SUITE_HELPERS - helper functions common to
|
|
# the test suite
|
|
# BEGIN_CASE / END_CASE - the test cases in the test suite. Each test
|
|
# case contains at least one function that is used to create the
|
|
# dispatch code.
|
|
#
|
|
# - test data file - file name in the form 'test_suite_xxxx.data'
|
|
# The test case parameters to to be used in execution of the test. The
|
|
# file name is used to replace the symbol 'TESTCASE_FILENAME' in the main
|
|
# code file above.
|
|
#
|
|
# A test data file consists of a sequence of paragraphs separated by
|
|
# a single empty line. Line breaks may be in Unix (LF) or Windows (CRLF)
|
|
# format. Lines starting with the character '#' are ignored
|
|
# (the parser behaves as if they were not present).
|
|
#
|
|
# Each paragraph describes one test case and must consist of: (1) one
|
|
# line which is the test case name; (2) an optional line starting with
|
|
# the 11-character prefix "depends_on:"; (3) a line containing the test
|
|
# function to execute and its parameters.
|
|
#
|
|
# A depends_on: line consists of a list of compile-time options
|
|
# separated by the character ':', with no whitespace. The test case
|
|
# is executed only if this compilation option is enabled in config.h.
|
|
#
|
|
# The last line of each paragraph contains a test function name and
|
|
# a list of parameters separated by the character ':'. Running the
|
|
# test case calls this function with the specified parameters. Each
|
|
# parameter may either be an integer written in decimal or hexadecimal,
|
|
# or a string surrounded by double quotes which may not contain the
|
|
# ':' character.
