# Python script for unit testing RGL grammars
|
|
|
|
## Usage
|
|
|
|
```
|
|
python path/to/unittest.py [-h] [-v] [--no-pmcfg] path/to/testfile.gftest (...)
|
|
```
|
|
|
|
The script must be located in a sibling directory
|
|
to the RGL `src` directory to work properly.
|
|
|
|
**Note:** On Windows use WSL (Windows Subsystem for Linux) to run `unittest.py` script, also replace the commented lines for Windows inside the script.
|
|
|
|
## Test format
|
|
|
|
The test file should look something like this:
|
|
|
|
```
|
|
LangSwe: jag sover i huset
|
|
LangEng: I sleep in the house
|
|
|
|
LangSwe: huset verkar stort
|
|
Lang: PhrUtt NoPConj (UttS (UseCl (TTAnt TPres ASimul) PPos (PredVP ...
|
|
```
|
|
|
|
This contains two tests: Every test should be separated by empty lines.
|
|
Every line starts with a language, followed by ":" and the sentence
|
|
(or the abstract syntax tree if the abstract grammar is specified).
|
|
|
|
You can also see an example in the file [`unittest-example.gftest`](unittest-example.gftest).
|
|
|
|
## No PMCFG
|
|
|
|
If your grammar is complex and takes long time to compile, you can try
|
|
the option `--no-pmcfg`, which tells GF to not build the parsing grammar.
|
|
|
|
Note however that in this case, every test case needs to contain a parse tree.
