Specify the CTest
ctest(1) dashboard client script.
Using Cobertura as the coverage generation within your multi-module Java project can generate a series of XML files.
The Cobertura Coverage parser expects to read the coverage data from a
single XML file which contains the coverage data for all modules.
Cobertura has a program with the ability to merge given
and then another program to generate a combined XML file from the previous
merged file. For command line testing, this can be done by hand prior to
CTest looking for the coverage files. For script builds,
CTEST_COVERAGE_COMMAND variable to point to a file which will
perform these same steps, such as a
run-coverage-and-consolidate.sh script is perhaps created by
configure_file() command and might contain the following code:
#!/usr/bin/env bash CoberturaFiles="$(find "/path/to/source" -name "cobertura.ser")" SourceDirs="$(find "/path/to/source" -name "java" -type d)" cobertura-merge --datafile coberturamerge.ser $CoberturaFiles cobertura-report --datafile coberturamerge.ser --destination . \ --format xml $SourceDirs
The script uses
find to capture the paths to all of the
files found below the project’s source directory. It keeps the list of files
and supplies it as an argument to the
cobertura-merge program. The
--datafile argument signifies where the result of the merge will be kept.
coberturamerge.ser file is then used to generate the XML report
cobertura-report program. The call to the cobertura-report
program requires some named arguments.
- path to the merged
- path to put the output files(s)
- file format to write output in: xml or html
The rest of the supplied arguments consist of the full paths to the
/src/main/java directories of each module within the source tree. These
directories are needed and should not be forgotten.
