12. Server¶
Cross-browser-tests-runner uses a server written using express
that manages testing state and processes.
12.1. Modes¶
12.1.1. Third Party Test Runners¶
$ ./node_modules/.bin/cbtr-server
The server would run and keep waiting. Hooks are provided that bind a third party test runner like Testem with the interfaces provided by the server to create and manage tests. See Using Testem for an example of how to use this mode.
12.1.2. Native Runner¶
Please see Native Runner for details on this home-grown tests runner.
$ ./node_modules/.bin/cbtr-server --native-runner [--config <path-to-settings-file>]
12.1.2.1. Debugging Mode¶
If the --config
option is not provided, or there are no browsers/testing information specified in the settings file mentioned, the server would keep running. A user then can open test HTML files on a local browser. In this mode, you can debug your tests before running the tests on a cross-browser testing platform. For example, if the server is listening on port 7982
, and tests.html
exists in the root directory of your project, you can open http://127.0.0.1:7982/tests.html
in a local browser.
12.1.2.2. CI Mode¶
The server runs all the tests and exits if the following are provided in the input settings file:
- JS browsers and
test_file
(Parameters) parameter, or - Selenium browsers,
test_file
(Parameters), andtest_script
(See Parameters) parameters
12.2. Usage¶
$ ./node_modules/.bin/cbtr-server [--help|-h] [--config|-c <config-file>] [--native-runner|-n] [--errors-only|-e] [--omit-traces|-o] [--error-reports-only|-E] [--omit-report-traces|-O]
Defaults:
config cbtr.json in project root, or CBTR_SETTINGS env var
native-runner false
errors-only false
omit-traces false
error-reports-only false
omit-report-traces false
Options:
help print this help
config cross-browser-tests-runner settings file
native-runner if the server should work as native test runner
errors-only (native runner only) print only the specs that failed
omit-traces (native runner only) print only the error message and no stack traces
error-reports-only (native runner only) report only the error specs from browser
omit-report-traces (native runner only) do not include stack traces in reports sent by browser
12.2.1. Important Options¶
NOTE: Please note that all of the following apply to native runner mode only
errors-only
: use this if you are interested in looking at only the failed test specs/suitesomit-traces
: use this if you are interested in the failure messages only and not the stack traceerror-reports-only
: use this if you want to send data of only the failed test specs/suites from the browseromit-report-traces
: use this if you want to not send stack traces of failures from the browser
First two are aimed at removing clutter in the output. Next two are aimed at reducing the size of test results data sent by browser.
