class="hash-link" aria-label="Direct link to Overview" title="Direct link to Overview"></a></h2><p>Apache BookKeeper is a well adopted software project with a strong commitment to testing.
Consequently, it has many testing-related needs. It requires precommit tests to ensure
code going to the repository meets a certain quality bar and it requires ongoing postcommit
tests to make sure that more subtle changes which escape precommit are nonetheless caught.
This document outlines how to write tests, which tests are appropriate where, and when tests
are run, with some additional information about the testing systems at the bottom.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="testing-scenarios">Testing Scenarios<a href="#testing-scenarios" class="hash-link" aria-label="Direct link to Testing Scenarios" title="Direct link to Testing Scenarios"></a></h2><p>With the tools at our disposal, we have a good set of utilities which we can use to verify
BookKeeper correctness. To ensure an ongoing high quality of code, we use precommit and postcommit
testing.</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="precommit">Precommit<a href="#precommit" class="hash-link" aria-label="Direct link to Precommit" title="Direct link to Precommit"></a></h3><p>For precommit testing, BookKeeper uses GitHub Actions to ensure that pull requests meet a certain quality bar.
These precommits verify correctness via unit/integration tests.</p><p>In case of failures, you can re-run failing checks commenting <code>rerun failure checks</code> in the pull.
More details on GitHub actions <a href="https://github.com/apache/bookkeeper/tree/master/.github/workflows/bot.yml" target="_blank" rel="noopener noreferrer">here</a></p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="postcommit">Postcommit<a href="#postcommit" class="hash-link" aria-label="Direct link to Postcommit" title="Direct link to Postcommit"></a></h3><p>Currently in postcommit, we re-run precommit tests against both master and the most recent release branch.
In this way we can ensure also the main branches are not broken.</p></article></div><div class="col col--2"><div class="tableOfContents_bqdL thin-scrollbar"><ul class="table-of-contents table-of-contents__left-border"><li><a href="#overview" class="table-of-contents__link toc-highlight">Overview</a></li><li><a href="#testing-scenarios" class="table-of-contents__link toc-highlight">Testing Scenarios</a><ul><li><a href="#precommit" class="table-of-contents__link toc-highlight">Precommit</a></li><li><a href="#postcommit" class="table-of-contents__link toc-highlight">Postcommit</a></li></ul></li></ul></div></div></div></main></div><footer class="footer footer--dark"><div class="container container-fluid"><div class="row footer__links"><div class="col footer__col"><div class="footer__title">Documentation</div><ul class="footer__items clean-list"><li class="footer__item"><a class="footer__link-item" href="/docs/overview">Overview</a></li><li class="footer__item"><a class="footer__link-item" href="/docs/getting-started/installation">Getting started</a></li><li class="footer__item"><a class="footer__link-item" href="/docs/deployment/manual">Deployment</a></li><li class="footer__item"><a class="footer__link-item" href="/docs/admin/bookies">Administration</a></li><li class="footer__item"><a class="footer__link-item" href="/docs/api/overview">API</a></li><li class="footer__item"><a class="footer__link-item" href="/docs/security/overview">Security</a></li><li class="footer__item"><a class="footer__link-item" href="/docs/development/protocol">Development</a></li><li class="footer__item"><a class="footer__link-item" href="/docs/reference/config">Reference</a></li></ul></div><div class="col footer__col"><div class="footer__title">Community</div><ul class="footer__items clean-list"><li class="footer__item"><a class="footer__link-item" href="/community/mailing-lists">Mailing lists</a></li><li class="footer__item"><a class="footer__link-item" href="/community/slack">Slack</a></li><li class="footer__item"><a href="https://github.com/apache/bookkeeper" target="_blank" rel="noopener noreferrer" class="footer__link-item">Github<svg width="13.5" height="13.5" aria-hidden="true" viewBox="0 0 24 24" class="iconExternalLink_nPIU"><path fill="currentColor" d="M21 13v10h-21v-19h12v2h-10v15h17v-8h2zm3-12h-10.988l4.035 4-6.977 7.07 2.828 2.828 6.977-7.07 4.125 4.172v-11z"></path></svg></a></li><li class="footer__item"><a href="https://twitter.com/asfbookkeeper" target="_blank" rel="noopener noreferrer" class="footer__link-item">Twitter<svg width="13.5" height="13.5" aria-hidden="true" viewBox="0 0 24 24" class="iconExternalLink_nPIU"><path fill="currentColor" d="M21 13v10h-21v-19h12v2h-10v15h17v-8h2zm3-12h-10.988l4.035 4-6.977 7.07 2.828 2.828 6.977-7.07 4.125 4.172v-11z"></path></svg></a></li></ul></div><div class="col footer__col"><div class="footer__title">Project</div><ul class="footer__items clean-list"><li class="footer__item"><a class="footer__link-item" href="/project/who">Who are we?</a></li><li class="footer__item"><a class="footer__link-item" href="/project/bylaws">Bylaws</a></li><li class="footer__item"><a href="https://apache.org/licenses" target="_blank" rel="noopener noreferrer" class="footer__link-item">License<svg width="13.5" height="13.5" aria-hidden="true" viewBox="0 0 24 24" class="iconExternalLink_nPIU"><path fill="currentColor" d="M21 13v10h-21v-19h12v2h-10v15h17v-8h2zm3-12h-10.988l4.035 4-6.977 7.07 2.828 2.828 6.977-7.07 4.125 4.172v-11z"></path></svg></a></li><li class="footer__item"><a class="footer__link-item" href="/project/privacy">Privacy policy</a></li><li class="footer__item"><a href="https://www.apache.org/foundation/sponsorship.html" target="_blank" rel="noopener noreferrer" class="footer__link-item">Sponsorship<svg width="13.5" height="13.5" aria-hidden="true" viewBox="0 0 24 24" class="iconExternalLink_nPIU"><path fill="currentColor" d="M21 13v10h-21v-19h12v2h-10v15h17v-8h2zm3-12h-10.988l4.035 4-6.977 7.07 2.828 2.828 6.977-7.07 4.125 4.172v-11z"></path></svg></a></li><li class="footer__item"><a href="https://www.apache.org/foundation/thanks.html" target="_blank" rel="noopener noreferrer" class="footer__link-item">Thanks<svg width="13.5" height="13.5" aria-hidden="true" viewBox="0 0 24 24" class="iconExternalLink_nPIU"><path fill="currentColor" d="M21 13v10h-21v-19h12v2h-10v15h17v-8h2zm3-12h-10.988l4.035 4-6.977 7.07 2.828 2.828 6.977-7.07 4.125 4.172v-11z"></path></svg></a></li></ul></div></div><div class="footer__bottom text--center"><div class="footer__copyright"><footer class="footer">
