# Debugging Tests Tips
|
||||
|
||||
## How to run & execute a specific test without anything else to keep the feedback loop short?
|
||||
|
||||
There is a script called run-single-test.sh in the scripts folder whose parameter takes a REGEX and an optional test number.
|
||||
|
||||
For example, running the following command will output an interactive list from which you can select a test. It takes this form:
|
||||
|
||||
`run-single-test.sh [OPTION]... <test_regex> <test_number>`
|
||||
|
||||
It will then build & run in the debugger for you.
|
||||
|
||||
```bash
|
||||
./scripts/run-single-test.sh test-tokenizer
|
||||
```
|
||||
|
||||
An example of a single test output is shown below. You will get either a green TEST PASS or a red TEST FAIL if a particular test is working or not. This shorter feedback loop will hopefully make it easier for you to figure out the problem you are trying to solve.
|
||||
|
||||
```bash
|
||||
$ ./scripts/run-single-test.sh test 24
|
||||
~/gitextern/llama.cpp ~/gitextern/llama.cpp
|
||||
|
||||
... prepping cmake environment ...
|
||||
... building test binaries ...
|
||||
... running test ...
|
||||
|
||||
Ran Test #24: test-eval-callback
|
||||
Command: /home/mofosyne/gitextern/llama.cpp/build-ci-debug/bin/eval-callback "--hf-repo" "ggml-org/models" "--hf-file" "tinyllamas/stories260K.gguf" "--model" "stories260K.gguf" "--prompt" "hello" "--seed" "42" "-ngl" "0"
|
||||
TEST PASS
|
||||
```
|
||||
|
||||
For further reference use `run-single-test.sh -h` to print help.
|
||||
|
||||
### How does the script work?
|
||||
|
||||
This is similar to `debug-test.sh` so you can follow the similar guide in this page for similar process. Just run the command directly rather than though gdb.

To just execute a test and get back a PASS or FAIL message run:
|
||||
|
||||
```bash
|
||||
./scripts/debug-test.sh test-tokenizer
|
||||
```
|
||||
|
||||
To test in GDB use the `-g` flag to enable gdb test mode.
|
||||
|
||||
```bash
|
||||
./scripts/debug-test.sh -g test-tokenizer
|
||||
|
||||
# Once in the debugger, i.e. at the chevrons prompt, setting a breakpoint could be as follows:
|
||||
>>> b main
|
||||
```
|
||||
|
||||
To speed up the testing loop, if you know your test number you can just run it similar to below:
|
||||
|
||||
```bash
|
||||
./scripts/debug-test.sh test 23
|
||||
```
|
||||
|
