Some `deno_std` tests were failing to print output that was resolved
after the last test finished. In addition, output printed before tests
began would sometimes appear above the "running X tests ..." line, and
sometimes below it depending on timing.
We now guarantee that all output is flushed before and after tests run,
making the output consistent.
Pre-test and post-test output are captured in `------ pre-test output
------` and `------ post-test output ------` blocks to differentiate
them from the regular output blocks.
Here's an example of a test (that is much noisier than normal, but an
example of what the output will look like):
```
Check ./load_unload.ts
------- pre-test output -------
load
----- output end -----
running 1 test from ./load_unload.ts
test ...
------- output -------
test
----- output end -----
test ... ok ([WILDCARD])
------- post-test output -------
unload
----- output end -----
```
As we add tracing to more types of runtime activity, `--trace-ops` is
less useful of a name. `--trace-leaks` better reflects that this feature
traces both ops and timers, and will eventually trace resource opening
as well.
This keeps `--trace-ops` as an alias for `--trace-leaks`, but prints a
warning to the console suggesting migration to `--trace-leaks`.
One test continues to use `--trace-ops` to test the deprecation warning.

- Removes the origin call, since all origins are the same for an isolate
(ie: the main module)
- Collects the `TestDescription`s and sends them all at the same time
inside of an Arc, allowing us to (later on) re-use these instead of
cloning.
Needs a follow-up pass to remove all the cloning, but that's a thread
that is pretty long to pull

Gets us closer to solving #20707.
Rewrites the `TestEventSender`:
- Allow for explicit creation of multiple streams. This will allow for
one-std{out,err}-per-worker
- All test events are received along with a worker ID, allowing for
eventual, proper parallel threading of test events.
In theory this should open up proper interleaving of test output,
however that is left for a future PR.
I had some plans for a better performing synchronization primitive, but
the inter-thread communication is tricky. This does, however, speed up
the processing of large numbers of tests 15-25% (possibly even more on
100,000+).
Before
```
ok | 1000 passed | 0 failed (32ms)
ok | 10000 passed | 0 failed (276ms)
```
After
```
ok | 1000 passed | 0 failed (25ms)
ok | 10000 passed | 0 failed (230ms)
```
The format of the sanitizers will change a little bit:
- If multiple async ops leak and traces are on, we repeat the async op
header once per stack trace.
- All leaks are aggregated under a "Leaks detected:" banner as the new
timers are eventually going to be added, and these are neither ops nor
resources.
- `1 async op` is now `An async op`
- If ops and resources leak, we show both (rather than op leaks masking
resources)
Follow-on to https://github.com/denoland/deno/pull/22226
Splitting the sleep and interval ops allows us to detect an interval
timer. We also remove the use of the `op_async_void_deferred` call.
A future PR will be able to split the op sanitizer messages for timers
and intervals.
Removes the `FileFetcher`'s internal cache because I don't believe it's
necessary (we already cache this kind of stuff in places like deno_graph
or config files in different places). Removing it fixes this bug because
this functionality was already implemented in deno_graph and lowers
memory usage of the CLI a little bit.
This moves the op sanitizer descriptions into Rust code and prepares for
eventual op import from `ext:core/ops`. We cannot import these ops from
`ext:core/ops` as the testing infrastructure ops are not always present.
Changes:
- Op descriptions live in `cli` code and are currently accessible via an
op for the older sanitizer code
- `phf` dep moved to workspace root so we can use it here
- `ops.op_XXX` changed to to `op_XXX` to prepare for op imports later
on.
Step 1 of the Rustification of sanitizers, which unblocks the faster
timers.
This replaces the resource sanitizer with a Rust one, using the new APIs
in deno_core.
We were calling `expand_glob` on our excludes, which is very expensive
and unnecessary because we can pattern match while traversing instead.
1. Doesn't expand "exclude" globs. Instead pattern matches while walking
the directory.
2. Splits up the "include" into base paths and applicable file patterns.
This causes less pattern matching to occur because we're only pattern
matching on patterns that might match and not ones in completely
unrelated directories.
This commit adds `--unstable-hmr` flag, that enabled Hot Module Replacement.
This flag works like `--watch` and accepts the same arguments. If
HMR is not possible the process will be restarted instead.
Currently HMR is only supported in `deno run` subcommand.
Upon HMR a `CustomEvent("hmr")` will be dispatched that contains
information which file was changed in its `details` property.

This commit introduces "WatcherCommunicator" struct that
is used facilitate bi-directional communication between CLI
file watcher and the watched function.
Prerequisite for https://github.com/denoland/deno/pull/20876
Previously:
```rust
pub struct TestDefinition {
pub id: String,
pub name: String,
pub range: SourceRange,
pub steps: Vec<TestDefinition>,
}
pub struct TestDefinitions {
pub discovered: Vec<TestDefinition>,
pub injected: Vec<lsp_custom::TestData>,
pub script_version: String,
}
```
Now:
```rust
pub struct TestDefinition {
pub id: String,
pub name: String,
pub range: Option<Range>,
pub is_dynamic: bool, // True for 'injected' module, not statically detected but added at runtime.
pub parent_id: Option<String>,
pub step_ids: HashSet<String>,
}
pub struct TestModule {
pub specifier: ModuleSpecifier,
pub script_version: String,
pub defs: HashMap<String, TestDefinition>,
}
```
Storing the test tree as a literal tree diminishes the value of IDs,
even though vscode stores them that way. This makes all data easily
accessible from `TestModule`. It unifies the interface between
'discovered' and 'injected' tests. This unblocks some enhancements wrt
syncing tests between the LSP and extension, such as this TODO:
61f08d5a71/client/src/testing.ts (L251-L259)
and https://github.com/denoland/vscode_deno/issues/900. We should also
get more flexibility overall.
`TestCollector` is cleaned up, now stores a `&mut TestModule` directly
and registers tests as it comes across them with
`TestModule::register()`. This method ensures sanity in the redundant
data from having both of `TestDefinition::{parent_id,step_ids}`.
All of the messy conversions between `TestDescription`,
`LspTestDescription`, `TestDefinition`, `TestData` and `TestIdentifier`
are cleaned up. They shouldn't have been using `impl From` and now the
full list of tests is available to their implementations.
This PR adds a test reporter for the [Test Anything
Protocol](https://testanything.org).
It makes the following implementation decisions:
- No TODO pragma, as there is no such marker in `Deno.test`
- SKIP pragma for `ignore`d tests
- Test steps are treated as TAP14 subtests
- Support for this in consumers seems spotty
- Some consumers will incorrectly interpret these markers, resulting in
unexpected output
- Considering the lack of support, and to avoid implementation
complexity,
subtests are at most one level deep (all test steps are in the same
subtest)
- To accommodate consumers that use comments to indicate test-suites
(unspecced)
- The test module path is output as a comment
- This is disabled for `--parallel` testing
- Failure diagnostics are output as JSON, which is also valid YAML
- The structure is not specified, so the format roughly follows the spec
example:
```
---
message: "Failed with error 'hostname peebles.example.com not found'"
severity: fail
found:
hostname: 'peebles.example.com'
address: ~
wanted:
hostname: 'peebles.example.com'
address: '85.193.201.85'
at:
file: test/dns-resolve.c
line: 142
...
```
This commit adds a "dot" reporter to "deno test" subcommand,
that can be activated using "--dot" flag.
It provides a concise output using:
- "." for passing test
- "," for ignored test
- "!" for failing test
User output is silenced and not printed to the console.
In non-TTY environments each result is printed on a separate line.
