Running tests

R13B03以后 OTP的模块加入了大量的测试模块,这些模块都是common_test的使用例子. 我们可以学到的2点 1. 如何编写common_test 2. 如何养成好习惯,为我们自己的工程编写测试案例.

以下是如何允许测试案例:

Running tests
Building

Build the tests like this

make release_tests

Running

To run the test first do:

cd release/tests/test_server

and then start Erlang:

$ERL_TOP/bin/erl

Install the ts framework

ts:install().

To run all test suites do

ts:run().

Note that running all tests will require several hours, so you may want to run the test cases for a single application

ts:run(Application, [batch]).

or even part of the test suite for an application, for example

ts:run(emulator, bs, [batch]).

to run all test suite modules starting with bs (i.e. all modules that test the bit syntax).

To run a specific test case in a module, the full name of the module and test case must be spelled out:

ts:run(emulator, bs_bincomp_SUITE, byte_aligned, [batch]).

Run ts:help() to show some help.

There will currently be 15 or so failed test cases in the kernel application.
Examining the results

Open the file release/test/test_server/index.html in a web browser. Or open release/test/test_server/last_test.html when a test suite is running to examine the results so far for the currently executing test suite.
