本教程详细介绍了使用 fx test 命令的调试工作流
和 Fuchsia 调试程序 (zxdb)。
如需详细了解如何使用 zxdb 调试测试，请参阅 使用 zxdb 调试测试
了解测试用例
储油站
Rust 测试由 Rust 测试运行程序执行。取消点赞
gTest 或 gUnit 运行程序，Rust 测试运行程序默认运行
多个测试用例。这样在使用
--break-on-failure 功能。如需详细了解
调试并行测试流程，请参见
并行执行测试用例。并行测试
支持进程。
下面是一个基于一些样本的示例 Rust 测试代码：
...
let mut log_helper2 = LogSinkHelper::new(&directory);
log_helper2.write_log("my msg1");
log_helper.write_log("my msg2");
let mut expected = vec!["my msg1".to_owned(), "my msg3".to_owned()];
expected.sort();
let mut actual = vec![recv_logs.next().await.unwrap(), recv_logs.next().await.unwrap()];
actual.sort();
assert_eq!(expected, actual);
...
您可以使用 fx set 将此测试目标添加到您的构建图中：
fx set workbench_eng.x64 --with-tests //src/diagnostics/archivist:tests
C++
默认情况下，gTest 测试运行程序会按顺序执行测试用例，因此只有一个
同时调试测试失败情况。你可以并行执行多个测试用例
在 fx test 命令中添加 --parallel-cases 标志。
下面是一个基于一些样本的示例 C++ 测试代码：
// Inject 1 process.
auto process1 = std::make_unique<MockProcess>(nullptr, kProcessKoid1, kProcessName1);
process1->AddThread(kProcess1ThreadKoid1);
harness.debug_agent()->InjectProcessForTest(std::move(process1));
// And another, with 2 threads.
auto process2 = std::make_unique<MockProcess>(nullptr, kProcessKoid2, kProcessName2);
process2->AddThread(kProcess2ThreadKoid1);
process2->AddThread(kProcess2ThreadKoid2);
harness.debug_agent()->InjectProcessForTest(std::move(process2));
reply = {};
remote_api->OnStatus(request, &reply);
ASSERT_EQ(reply.processes.size(), 3u); // <-- This will fail, since reply.processes.size() == 2
EXPECT_EQ(reply.processes[0].process_koid, kProcessKoid1);
EXPECT_EQ(reply.processes[0].process_name, kProcessName1);
...
您可以使用 fx set 将此测试目标添加到您的构建图中：
fx set workbench_eng.x64 --with-tests //src/developer/debug:tests

使用 fx test --break-on-failure 命令执行测试，例如：

检查失败情况

该示例包含一个测试失败问题，因此 Rust 测试会在abort
失败，zxdb 会注意到并报告此异常。zxdb 还会分析通话
取消堆栈，方便地让我们直接进入源代码
失败了您可以查看当前框架中的其他代码行
使用 list，例如：
[zxdb] list
533 expected.sort();
534
535 let mut actual = vec![recv_logs.next().await.unwrap(), recv_logs.next().await.unwrap()];
536 actual.sort();

您运行的所有命令都位于第 17 帧的上下文中，如 ▶ 所示。
您可以通过一些额外的上下文再次列出源代码：
[zxdb] list -c 10
528 let mut log_helper2 = LogSinkHelper::new(&directory);
529 log_helper2.write_log("my msg1");
530 log_helper.write_log("my msg3");
531
532 let mut expected = vec!["my msg1".to_owned(), "my msg2".to_owned()];
533 expected.sort();
534
535 let mut actual = vec![recv_logs.next().await.unwrap(), recv_logs.next().await.unwrap()];
536 actual.sort();
537
▶ 538 assert_eq!(expected, actual);
539
540 // can log after killing log sink proxy
541 log_helper.kill_log_sink();
542 log_helper.write_log("my msg1");
543 log_helper.write_log("my msg2");
544
545 assert_eq!(
546 expected,
547 vec! {recv_logs.next().await.unwrap(),recv_logs.next().await.unwrap()}
548 );
[zxdb]
要找出测试失败的原因，可以输出一些变量，看看
情况。actual 帧包含一个局部变量，
应包含一些通过对write_log
log_helper 和 log_helper2 实例，并通过
mpsc 频道 recv_logs：
[zxdb] print expected
vec!["my msg1", "my msg3"]
[zxdb] print actual
vec!["my msg1", "my msg2"]
该测试的预期似乎有点不正确。符合预期
"my msg3" 应该是第二个字符串，但实际上
"my msg2"。您可以更正测试，预计会得到 "my msg2"。现在，您可以
从测试中分离出来以继续并完成测试套件：
[zxdb] quit

请注意，▶ 指向测试的源代码帧，表明：
所有命令都在此上下文中执行。你可以选择其他画面
将 frame 命令与堆栈轨迹中的关联编号搭配使用。
要找出测试失败的原因，可以输出一些变量，看看
情况。reply 帧包含一个局部变量，该变量应该
由对 remote_api->OnStatus 的函数调用进行填充：
[zxdb] print reply
{
processes = {
[0] = {
process_koid = 4660
process_name = "process-1"
components = {}
threads = {
[0] = {
id = {process = 4660, thread = 1}
name = "test thread"
state = kRunning
blocked_reason = kNotBlocked
stack_amount = kNone
frames = {}
}
}
}
[1] = {
process_koid = 22136
process_name = "process-2"
components = {}
threads = {
[0] = {
id = {process = 22136, thread = 1}
name = "test thread"
state = kRunning
blocked_reason = kNotBlocked
stack_amount = kNone
frames = {}
}
[1] = {
id = {process = 22136, thread = 2}
name = "test thread"
state = kRunning
blocked_reason = kNotBlocked
stack_amount = kNone
frames = {}
}
}
}
}
limbo = {}
breakpoints = {}
filters = {}
}
在输出中，您可以看到 reply 变量已填充了一些
信息，processes 向量的大小应如下所示：
等于 3。输出 reply 的成员变量以查看更多信息。
您还可以输出该矢量的大小方法（一般函数调用
支持尚未实现）：
[zxdb] print reply.processes
{
[0] = {
process_koid = 4660
process_name = "process-1"
components = {}
threads = {
[0] = {
id = {process = 4660, thread = 1}
name = "test thread"
state = kRunning
blocked_reason = kNotBlocked
stack_amount = kNone
frames = {}
}
}
}
[1] = {
process_koid = 22136
process_name = "process-2"
components = {}
threads = {
[0] = {
id = {process = 22136, thread = 1}
name = "test thread"
state = kRunning
blocked_reason = kNotBlocked
stack_amount = kNone
frames = {}
}
[1] = {
id = {process = 22136, thread = 2}
name = "test thread"
state = kRunning
blocked_reason = kNotBlocked
stack_amount = kNone
frames = {}
}
}
}
}
[zxdb] print reply.processes.size()
2
该测试的预期似乎有点不正确。仅您本人
注入了 2 个模拟进程，但测试预期应为 3 个。您只需
更新测试，预期 reply.processes 矢量的大小为
2 而不是 3。您现在可以使用 quit 关闭 zxdb，然后更新并修复
测试：
