[FR]: Allowing for inline update of test results to reduce number of lines printed to stdout

[shaurya-chandhoke]

Does the feature exist in the most recent commit?

Not that I'm aware of

Why do we need this feature?

It would be a great way to reduce the output for large test suites into succinct lines describing which ones have passed or failed.

Describe the proposal.

Currently every passing test will receive at least 2 lines as follows:

[ RUN      ]  SuiteA.Test1
[       OK ]  SuiteA.Test1 (0 ms)

It would be great if this instead happened with a carriage return so it updates within 1 line as follows

---

Test is executed

[ RUN      ]  SuiteA.Test1

Test result is passed and updates the current line it's on instead of writing to new line

[       OK ]  SuiteA.Test1 (0 ms)

---

Of course for failed tests this wouldn't apply as we would need to see the failure message.

Perhaps this feature could be a flag (i.e --gtest_succinct=true)

Is the feature specific to an operating system, compiler, or build system version?

No
