The Bio-Formats testing framework component contains most of the infrastructure to run automated tests against the data repository.
After checking out source code and building all the JAR files (see Obtaining and building Bio-Formats), switch to the test-suite component and run the tests using the ant test-automated target:
$ cd components/test-suite
$ ant -Dtestng.directory=$DATA/metamorph test-automated
where $DATA is the path to the full data repository.
Multiple options can be passed to the ant test-automated target by setting the testng.${option} option via the command line. Useful options are described below.
Mandatory option. Specifies the root of the data directory to be tested:
$ ant -Dtestng.directory=$DATA/metamorph test-automated
On Windows, the arguments to the test command must be quoted:
> ant "-Dtestng.directory=$DATA\metamorph" test-automated
Specifies the root of the directory containing the configuration files. This directory must have the same hierarchy as the one specified by testng.directory and contain .bioformats configuration files:
$ ant -Dtestng.directory=/path/to/data -Dtestng.configDirectory=/path/to/config test-automated
If no configuration directory is passed, the assumption is that it is the same as the data directory.
Specifies an optional suffix for the configuration files:
$ ant -Dtestng.directory=/path/to/data -Dtestng.configSuffix=win test-automated
Specifies the amount of memory to be allocated to the JVM:
$ ant -Dtestng.directory=$DATA -Dtestng.memory=4g test-automated
Default: 512m.
Specifies the number of threads to use for testing:
$ ant -Dtestng.directory=$DATA -Dtestng.threadCount=4 test-automated
Default: 1.
You should now see output similar to this:
Buildfile: build.xml

In most cases, test failures should be logged in the main console output as:
[testng] [2015-08-18 17:13:13,625] [pool-1-thread-1] SizeZ: FAILED (Series 0 (expected 2, actual 1))
To identify the file, look for the initialization line preceding the test failures under the same thread:
[testng] [2015-08-18 17:13:12,376] [pool-1-thread-1] Initializing /ome/data_repo/test_per_commit/ome-tiff/img_bk_20110701.ome.tif:
The console output is also recorded under components/test-suite/target as bio-formats-software-test-main-$DATE.log where “$DATE” is the date on which the tests started in “yyyy-MM-dd_hh-mm-ss” format. The detailed report of each thread is recorded under bio-formats-software-pool-$POOL-thread-$THREAD-main-$DATE.log
Configuration files can be generated for files or directories using the ant gen-config target. This generation target supports the same options as ant test-automated:
$ ant -Dtestng.directory=/path/to/data -Dtestng.configDirectory=/path/to/config -Dtestng.memory=4g -Dtestng.threadCount=6 gen-config
Tests for the Bio-Formats MATLAB toolbox are written using the xunit framework and are located under components/formats-gpl/test/matlab.
To run these tests, you will need to download or clone matlab-xunit, a xUnit framework with JUnit-compatible XML output. Then add this package together with the Bio-Formats MATLAB to your MATLAB path:
% Add the matlab-xunit toolbox to the MATLAB path
addpath('/path/to/matlab-xunit');
% Add the Bio-Formats MATLAB source to the MATLAB path
% For developers working against the source code
addpath('/path/to/bioformats/components/formats-gpl/matlab');
addpath('/path/to/bioformats/artifacts');
% For developers working against a built artifact, e.g. a release
% addpath('/path/to/bfmatlab');
You can run all the MATLAB tests using runxunit:
cd /path/to/bioformats/components/formats-gpl/test/matlab
runxunit
Individual test classes can be run by passing the name of the class:
cd /path/to/bioformats/components/formats-gpl/test/matlab
runxunit TestBfsave
Individual test methods can be run by passing the name of the class and the name of the method:
cd /path/to/bioformats/components/formats-gpl/test/matlab
runxunit TestBfsave:testLZW
Finally, to output the test results under XML format, you can use the -xmlfile option:
cd /path/to/bioformats/components/formats-gpl/test/matlab
runxunit -xmlfile test-output.xml
