| <h1 id="native_metric_tests" class="page-title">原生指标测试</h1> |
| |
| <p>原生指标测试通常用于执行硬件抽象层 (HAL) 或直接与较低级别的系统服务交互。要利用连续测试服务，应使用 <a href="https://github.com/google/benchmark" class="external">google-benchmark</a> 框架编译原生指标测试。</p> |
| |
| <h2 id="example">示例</h2> |
| |
| <p>请参阅示例原生测试模块设置，位于：<a href="https://android.googlesource.com/platform/bionic/+/master/benchmarks/bionic_benchmarks.cpp">bionic/benchmarks/bionic-benchmarks</a></p> |
| |
| <h2 id="summary_of_steps">步骤总结</h2> |
| |
| <ol> |
| <li>测试模块配置文件应使用 <code>BUILD_NATIVE_BENCHMARK</code> 编译规则，以便自动包含 google-benchmark 依赖项。</li> |
| <li><p>使用 make 命令编译测试模块：</p> |
| <pre class="prettyprint lang-shell"><code>make -j40 bionic-benchmarks |
| </code></pre></li> |
| <li><p>使用 Trade Federation 自动化测试框架自动安装和运行：</p> |
| <pre class="prettyprint"><code>make tradefed-all -j |
| tradefed.sh run template/local_min --template:map test=bionic-benchmarks |
| </code></pre></li> |
| <li><p>手动安装并运行，如下所示：</p> |
| |
| <ol> |
| <li><p>将生成的测试二进制文件推送到设备：</p> |
| <pre class="prettyprint"><code>adb push ${OUT}/data/benchmarktest/bionic-benchmarks/bionic-benchmarks32 \ |
| /data/benchmarktest/bionic-benchmarks/bionic-benchmarks32 |
| </code></pre></li> |
| <li><p>通过在设备上调用测试二进制文件执行测试：</p> |
| <pre class="prettyprint"><code>adb shell /data/benchmarktest/bionic-benchmarks/bionic-benchmarks32 |
| </code></pre></li> |
| </ol></li> |
