<p>Heron uses <a href="compiling-overview#installing-bazel">Bazel</a> for building

<p>Integration tests are divided into two categories:</p>
<ul>
<li><p>Functional integration tests</p>
<p>These integration tests are designed for testing the functionality of
Heron, such as topologies and groupings.
To run the functional integration tests on a Mac OS X, do the following:</p>
<pre><code class="hljs css language-bash">$ ./scripts/run_integration_test.sh
</code></pre></li>
<li><p>Failure integration tests</p>
<p>These integration tests are designed for testing recovery from failure/restart
in certain processes, such as Topology Manager and Metrics Manager.
To run the failure integration tests on a Mac OS X, do the following:</p>
<pre><code class="hljs css language-bash">$ bazel build --config=darwin integration_test/src/...
$ ./bazel-bin/integration_test/src/python/local_test_runner/<span class="hljs-built_in">local</span>-test-runner

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.<br/><br/>Apache®, the names of Apache projects, and the feather logo are either <a rel="external" href="https://www.apache.org/foundation/marks/list/">registered trademarks or trademarks</a> of the Apache Software Foundation in the United States and/or other countries.<br/><br/><div class="copyright-box">Copyright © 2023 the Apache Software Foundation, Apache Heron, Heron,
