-
-Toaster Testing Framework
-Yocto Project
-
-
-Rationale
-------------
-As Toaster contributions grow with the number of people that contribute code, verifying each patch prior to submitting upstream becomes a hard-to-scale problem for humans. We devised this system in order to run patch-level validation, trying to eliminate common problems from submitted patches, in an automated fashion.
-
-The Toaster Testing Framework is a set of Python scripts that provides an extensible way to write smoke and regression tests that will be run on each patch set sent for review on the toaster mailing list.
-
-
-Usage
-------------
-There are three main executable scripts in this directory.
-    *    runner.py  is designed to be run from the command line. It requires, as mandatory parameter, a branch name on poky-contrib, branch which contains the patches to be tested. The program will auto-discover the available tests residing in this directory by looking for unittest classes, and will run the tests on the branch dumping the output to the standard output. Optionally, it can take parameters inhibiting the branch checkout, or specifying a single test to be run, for debugging purposes.
-    *    launcher.py  is a designed to be run from a crontab or similar scheduling mechanism. It looks up a backlog file containing branches-to-test (named tasks in the source code), select the first one in FIFO manner, and launch runner.py on it. It will await for completion, and email the standard output and standard error dumps from the runner.py execution
-    *    recv.py  is an email receiver, designed to be called as a pipe from a .forward file. It is used to monitor a mailing list, for example, and add tasks to the backlog based on review requests coming on the mailing list.
-
-
-Installation
-------------
-As prerequisite, we expect a functioning email system on a machine with Python2.
-
-The broad steps to installation
-* set up the .forward on the receiving email account to pipe to the recv.py file
-* edit config.py and settings.json to alter for local installation settings
-* on email receive, verify backlog.txt to see that the tasks are received and marked for processing
-* execute launcher.py in command line to verify that a test occurs with no problems, and that the outgoing email is delivered
-* add launcher.py
-
-
-
-Contribute
-------------
-What we need are tests. Add your own tests to either tests.py file, or to a new file.
-Use "config.logger" to write logs that will make it to email.
-
-Commonly used code should be going to shellutils, and configuration to config.py.
-
-Contribute code by emailing patches to the list: toaster@yoctoproject.org (membership required)

-# Download the lastest firefox addon from http://release.seleniumhq.org/selenium-ide/
-# Then install it. You can also install firebug and firepath addon
-
-# 4. How to start writing a new case:
-# All you need to do is to implement the function test_xxx() and  pile it on.
-
-# 5. How to test with Chrome browser
-# Download/install chrome on host
-# Download chromedriver from https://code.google.com/p/chromedriver/downloads/list  according to your host type
-# put chromedriver in PATH, (e.g. /usr/bin/, bear in mind to chmod)
-# For windows host, you may put chromedriver.exe in the same directory as chrome.exe

-# DESCRIPTION
-# This is toaster automation base class and test cases file
-
-# History:
-# 2015.03.09  inital version
-# 2015.03.23  adding toaster_test.cfg, run_toastertest.py so we can run case by case from outside
-
-# Briefs:
-# This file is comprised of 3 parts:
-# I:   common utils like sorting, getting attribute.. etc
-# II:  base class part, which complies with unittest frame work and
-#      contains class selenium-based functions
-# III: test cases
-#      to add new case: just implement new test_xxx() function in class toaster_cases
-
-# NOTES for cases:
-# case 946:
-# step 6 - 8 needs to be observed using screenshots
-# case 956:
-# step 2 - 3 needs to be run manually

+# Running eventreplay tests
+
+These tests use event log files produced by bitbake <target> -w <event log file>
+You need to have event log files produced before running this tests.
+
+At the moment of writing this document tests use 2 event log files: zlib.events
+and core-image-minimal.events. They're not provided with the tests due to their
+significant size.
+
+Here is how to produce them:
+
+$ . oe-init-build-env
+$ rm -r tmp sstate-cache
+$ bitbake core-image-minimal -w core-image-minimal.events
+$ rm -rf tmp sstate-cache
+$ bitbake zlib -w zlib.events
+
+After that it should be possible to run eventreplay tests this way:
+
+$ EVENTREPLAY_DIR=./ DJANGO_SETTINGS_MODULE=toastermain.settings_test ../bitbake/lib/toaster/manage.py test -v2 tests.eventreplay
+
+Note that environment variable EVENTREPLAY_DIR should point to the directory with event log files.
