Description
Version
v26.3.0
Subsystem
test_runner
What steps will reproduce the bug?
echo "const test = require('node:test'); test('good test', (t) => { t.assert.equal(1, 1) })" > one.test.js
echo "const test = require('node:test'); test('bad test', (t) => { t.assert.equal(1, 2) })" > two.test.js
node --test --test-name-pattern=good *.test.js
How often does it reproduce? Is there a required condition?
always
What is the expected behavior? Why is that the expected behavior?
✔ good test (0.963084ms)
ℹ tests 1
ℹ suites 0
ℹ pass 1
ℹ fail 0
ℹ cancelled 0
ℹ skipped 0
ℹ todo 0
ℹ duration_ms 0.963084ms
The file two.test.js does not contain a single test that matches the --test-name-pattern, so should be skipped entirely, i.e. treated as if it doesn't exist.
What do you see instead?
✔ good test (0.963084ms)
✔ two.test.js (61.52275ms) <-- file with no matching tests reported (by file name) as passing
ℹ tests 2 <-- should be 1 test
ℹ suites 0
ℹ pass 2 <-- should be 1 pass
ℹ fail 0
ℹ cancelled 0
ℹ skipped 0
ℹ todo 0
ℹ duration_ms 68.503541 <-- should be 0.963084ms

Research direction
Start by running the reported command with one.test.js and two.test.js, then inspect the test_runner implementation and its existing tests for --test-name-pattern handling. Done means a file with no matching tests is omitted and the totals, pass count, and duration include only the matching good test.
