+# Image-based testing borrowed from vispy
+
+"""
+Procedure for unit-testing with images:
+
+1. Run unit tests at least once; this initializes a git clone of
+ pyqtgraph/test-data in ~/.pyqtgraph.
+
+2. Run individual test scripts with the PYQTGRAPH_AUDIT environment variable set:
+
+ $ PYQTGRAPH_AUDIT=1 python pyqtgraph/graphicsItems/tests/test_PlotCurveItem.py
+
+ Any failing tests will
+ display the test results, standard image, and the differences between the
+ two. If the test result is bad, then press (f)ail. If the test result is
+ good, then press (p)ass and the new image will be saved to the test-data
+ directory.
+
+3. After adding or changing test images, create a new commit:
+
+ $ cd ~/.pyqtgraph/test-data
+ $ git add ...
+ $ git commit -a
+
+4. Look up the most recent tag name from the `testDataTag` global variable
+ below. Increment the tag name by 1 and create a new tag in the test-data
+ repository:
+
+ $ git tag test-data-NNN
+ $ git push --tags origin master
+
+ This tag is used to ensure that each pyqtgraph commit is linked to a specific
+ commit in the test-data repository. This makes it possible to push new
+ commits to the test-data repository without interfering with existing
+ tests, and also allows unit tests to continue working on older pyqtgraph
+ versions.
+
+"""
+
+
+# This is the name of a tag in the test-data repository that this version of
+# pyqtgraph should be tested against. When adding or changing test images,
+# create and push a new tag and update this variable. To test locally, begin
+# by creating the tag in your ~/.pyqtgraph/test-data repository.

+PyQtGraph Release Procedure
+---------------------------
+
+1. Create a release-x.x.x branch
+
+2. Run pyqtgraph/tools/pg-release.py script (this has only been tested on linux)
+ - creates clone of master
+ - merges release branch into master
+ - updates version numbers in code
+ - creates pyqtgraph-x.x.x tag
+ - creates release commit
+ - builds documentation
+ - builds source package
+ - tests pip install
+ - builds windows .exe installers (note: it may be necessary to manually
+ copy wininst*.exe files from the python source packages)
+ - builds deb package (note: official debian packages are built elsewhere;
+ these locally-built deb packages may be phased out)
+
+3. test build files
+ - test setup.py, pip on OSX
+ - test setup.py, pip, 32/64 exe on windows
+ - test setup.py, pip, deb on linux (py2, py3)
+
+4. Run pg-release.py script again with --publish flag
+ - website upload
+ - github push + release
+ - pip upload
+
+5. publish
+ - update website
+ - mailing list announcement
+ - new conda recipe (http://conda.pydata.org/docs/build.html)
+ - contact various package maintainers
