can I log value in test?

[zzz6519003]

if I do tools/test.py test/parallel/test-stream2-transform.js to following code, I wanna see the value

assert.strictEqual(tx.readableLength, 10);
console.log(transformed);
assert.strictEqual(transformed, 10);

I usually do ./out/Debug/node ./xxx.js then directly see the output
