Package: avocado-framework
Avocado is a set of tools and libraries to help with automated testing.One can call it a test framework with benefits.  Native tests are written in
Python and they follow theunittestpattern, but any executable can
serve as a test.How does it work?You should first experience Avocado by using the test runner, that is, the
command line tool that will conveniently run your tests and collect their
results.To do so, please runavocadowith therunsub-command followed by a
test reference, which could be either a path to the file, or a recognizable
name:$ avocado run /bin/true

JOB TIME   : 1.52 sYou probably noticed that we used/bin/trueas a test, and in accordance
with our expectations, it passed! These are known asexec-test, but there
is also another type of test, which we callinstrumented tests.TipSee more at theTest typessection on theAvocado User’s Guide.Why should I use it?Multiple result formatsA regular run of Avocado will present the test results on standard output, a
nice and colored report useful for human beings. But results for machines can
also be generated.Check the job-results folder ($HOME/avocado/job-results/latest/) to see the
outputs.Currently we support, out of box, the following output formats:xUnit: an XML format that contains test results in a structured form,
and are used by other test automation projects, such as jenkins.JSON: a widely used data exchange format. The JSON Avocado plugin
outputs job information, similarly to the xunit output plugin.TAP: Provides the basic TAP (Test Anything Protocol) results,
currently in v12. Unlike most existing Avocado machine readable outputs
this one is streamlined (per test results).NoteYou can see the results of the latest job inside the folder$HOME/avocado/job-results/latest/. You can also specify at the command line
the options--xunit,--jsonor--tapfollowed by a filename.
Avocado will write the output on the specified filename.When it comes to outputs, Avocado is very flexible. You can check the variousoutput plugins. If you need something more sophisticated, visit ourplugins
section.Sysinfo data collectorAvocado comes with a sysinfo plugin, which automatically gathers some system
information per each job or even between tests. This is very helpful when
trying to identify the cause of a test failure.Check out the files stored at$HOME/avocado/job-results/latest/sysinfo/:$ ls $HOME/avocado/job-results/latest/sysinfo/pre/

replayed. The hash id can be partial, as long as the provided part corresponds
to the initial characters of the original job id and it is also unique enough.
Or, instead of the job id, you can use the string latest and Avocado will
replay the latest job executed.Example:$ avocado replay 825b86

jobs.

Theavocadocommand line tool has a builtinpluginscommand that lets you
list available plugins. The usage is pretty simple:$ avocado plugins
Plugins that add new commands (avocado.plugins.cli.cmd):
exec-path Returns path to Avocado bash libraries and exits.
run       Run one or more tests (native test, test alias, binary or script)
sysinfo   Collect system information
...
Plugins that add new options to commands (avocado.plugins.cli):
remote  Remote machine options for 'run' subcommand
journal Journal options for the 'run' subcommand

theAvocado User’s Guide.Utility librariesWhen writing tests, developers often need to perform basic tasks on OS and end
up having to implement these routines just to run they tests.Avocado hasmore than 40utility modulesthat helps you to perform basic
operations.Below a small subset of our utility modules:utils.vmimage: This utility provides a API to download/cache VM images
(QCOW) from the official distributions repositories.utils.memory: Provides information about memory usage.utils.cpu: Get information from the current’s machine CPU.utils.software_manager: Software package management library.utils.download: Methods to download URLs and regular files.utils.archive: Module to help extract and create compressed archives.Avocado Python APIIf the command-line is limiting you, then you can use our new API and
create custom jobs and test suites:importsysfromavocado.core.jobimportJobwithJob.from_config({'resolver.references':['/bin/true']})asjob:sys.exit(job.run())How to installIt is super easy, just run the follow command:$ pip3 install --user avocado-frameworkThis will install the avocado command in your home directory.NoteFor more details and alternative methods, please visit theInstalling section on Avocado User’s GuideDocumentationPlease use the following links for full documentation, including installation
