From 98de31e836a04ccc8f5f9acd90b9ba0803a24ab5 Mon Sep 17 00:00:00 2001 From: Stavros Aronis Date: Fri, 18 Jun 2010 03:44:25 +0300 Subject: Test suites for Dialyzer This is a transcription of most of the cvs.srv.it.uu.se:/hipe repository dialyzer_tests into test suites that use the test server framework. See README for information on how to use the included scripts for modifications and updates. When testing Dialyzer it's important that several OTP modules are included in the plt. The suites takes care of that too. --- .../test/r9c_tests_SUITE_data/src/inets/http.erl | 260 +++++++++++++++++++++ 1 file changed, 260 insertions(+) create mode 100644 lib/dialyzer/test/r9c_tests_SUITE_data/src/inets/http.erl (limited to 'lib/dialyzer/test/r9c_tests_SUITE_data/src/inets/http.erl') diff --git a/lib/dialyzer/test/r9c_tests_SUITE_data/src/inets/http.erl b/lib/dialyzer/test/r9c_tests_SUITE_data/src/inets/http.erl new file mode 100644 index 0000000000..764e7fb092 --- /dev/null +++ b/lib/dialyzer/test/r9c_tests_SUITE_data/src/inets/http.erl @@ -0,0 +1,260 @@ +%% ``The contents of this file are subject to the Erlang Public License, +%% Version 1.1, (the "License"); you may not use this file except in +%% compliance with the License.
