<h1 id="the-test-command"><a class="header" href="#the-test-command">The test command</a></h1>
|
||
|
|
<p>When writing a book, you sometimes need to automate some tests. For example,
|
||
|
|
<a href="https://doc.rust-lang.org/stable/book/">The Rust Programming Book</a> uses a lot
|
||
|
|
of code examples that could get outdated. Therefore it is very important for
|
||
|
|
them to be able to automatically test these code examples.</p>
|
||
|
|
<p>mdBook supports a <code>test</code> command that will run all available tests in a book. At
|
||
|
|
the moment, only Rust tests are supported.</p>
|
||
|
|
<h4 id="disable-tests-on-a-code-block"><a class="header" href="#disable-tests-on-a-code-block">Disable tests on a code block</a></h4>
|
||
|
|
<p>rustdoc doesn't test code blocks which contain the <code>ignore</code> attribute:</p>
|
||
|
|
<pre><code>```rust,ignore
|
||
|
|
fn main() {}
|
||
|
|
```
|
||
|
|
</code></pre>
|
||
|
|
<p>rustdoc also doesn't test code blocks which specify a language other than Rust:</p>
|
||
|
|
<pre><code>```markdown
|
||
|
|
**Foo**: _bar_
|
||
|
|
```
|
||
|
|
</code></pre>
|
||
|
|
<p>rustdoc <em>does</em> test code blocks which have no language specified:</p>
|
||
|
|
<pre><code>```
|
||
|
|
This is going to cause an error!
|
||
|
|
```
|
||
|
|
</code></pre>
|
||
|
|
<h4 id="specify-a-directory"><a class="header" href="#specify-a-directory">Specify a directory</a></h4>
|
||
|
|
<p>The <code>test</code> command can take a directory as an argument to use as the book's root
|
||
|
|
instead of the current working directory.</p>
|
||
|
|
<pre><code class="language-bash">mdbook test path/to/book
|
||
|
|
</code></pre>
|
||
|
|
<h4 id="--library-path"><a class="header" href="#--library-path">--library-path</a></h4>
|
||
|
|
<p>The <code>--library-path</code> (<code>-L</code>) option allows you to add directories to the library
|
||
|
|
search path used by <code>rustdoc</code> when it builds and tests the examples. Multiple
|
||
|
|
directories can be specified with multiple options (<code>-L foo -L bar</code>) or with a
|
||
|
|
comma-delimited list (<code>-L foo,bar</code>). The path should point to the Cargo
|
||
|
|
<a href="https://doc.rust-lang.org/cargo/guide/build-cache.html">build cache</a> <code>deps</code> directory that
|
||
|
|
contains the build output of your project. For example, if your Rust project's book is in a directory
|
||
|
|
named <code>my-book</code>, the following command would include the crate's dependencies when running <code>test</code>:</p>
|
||
|
|
<pre><code class="language-shell">mdbook test my-book -L target/debug/deps/
|
||
|
|
</code></pre>
|
||
|
|
<p>See the <code>rustdoc</code> command-line <a href="https://doc.rust-lang.org/rustdoc/command-line-arguments.html#-l--library-path-where-to-look-for-dependencies">documentation</a>
|
||
|
|
for more information.</p>
|
||
|
|
<h4 id="--dest-dir"><a class="header" href="#--dest-dir">--dest-dir</a></h4>
|
||
|
|
<p>The <code>--dest-dir</code> (<code>-d</code>) option allows you to change the output directory for the
|
||
|
|
book. Relative paths are interpreted relative to the book's root directory. If
|
||
|
|
not specified it will default to the value of the <code>build.build-dir</code> key in
|
||
|
|
<code>book.toml</code>, or to <code>./book</code>.</p>
|
||
|
|
<h4 id="--chapter"><a class="header" href="#--chapter">--chapter</a></h4>
|
||
|
|
<p>The <code>--chapter</code> (<code>-c</code>) option allows you to test a specific chapter of the
|
||
|
|
book using the chapter name or the relative path to the chapter.</p>
