This flag is passed automatically with the (new) -v flag for TinyGo. For
example, this prints all the test outputs:
$ tinygo test -v crypto/md5
=== RUN TestGolden
--- PASS: TestGolden
=== RUN TestGoldenMarshal
--- PASS: TestGoldenMarshal
=== RUN TestLarge
--- PASS: TestLarge
=== RUN TestBlockGeneric
--- PASS: TestBlockGeneric
=== RUN TestLargeHashes
--- PASS: TestLargeHashes
PASS
ok crypto/md5 0.002s
This prints just a summary:
$ tinygo test crypto/md5
PASS
ok crypto/md5 0.002s
(The superfluous 'PASS' message may be removed in the future).
This is especially useful when testing a large number of packages:
$ tinygo test crypto/md5 crypto/sha1 crypto/sha256 crypto/sha512
PASS
ok crypto/md5 0.002s
PASS
ok crypto/sha1 0.043s
PASS
ok crypto/sha256 0.002s
PASS
ok crypto/sha512 0.003s
At the moment, the -test.v flag is not supplied to binaries running in
emulation. I intend to fix this after
https://github.com/tinygo-org/tinygo/pull/2038 lands by refactoring
runPackageTest, Run, and runTestWithConfig in the main package which all
do something similar.
This commit makes the output of `tinygo test` similar to that of `go
test`. It changes the following things in the process:
* Running multiple tests in a single command is now possible. They
aren't paralellized yet.
* Packages with no test files won't crash TinyGo, instead it logs it
in the same way the Go toolchain does.
For example, for running tests with -target=wasm or
-target=cortex-m-qemu. It looks at the output to determine whether tests
were successful in the absence of a status code.
There were a few problems with the go/packages package. While it is more
or less designed for our purpose, it didn't work quite well as it didn't
provide access to indirectly imported packages (most importantly the
runtime package). This led to a workaround that sometimes broke
`tinygo test`.
This PR contains a number of related changes:
* It uses `go list` directly to retrieve the list of packages/files to
compile, instead of relying on the go/packages package.
* It replaces our custom TestMain replace code with the standard code
for running tests (generated by `go list`).
* It adds a dummy runtime/pprof package and modifies the testing
package, to get tests to run again with the code generated by
`go list`.
Implements nearly all of the test logging methods for both T and B
structs. Majority of the code has been copied from:
golang.org/src/testing/testing.go
then updated to match the existing testing.go structure.
Code structure/function/method order mimics upstream.
Both FailNow() and SkipNow() cannot be completely implemented,
because they require an early exit from the goroutine. Instead,
they call Error() to report the limitation.
This incomplete implementation allows more detailed test logging and
increases compatiblity with upstream.
