| # Developer notes for working on kernel |
| |
| ## How to test changes on pkg/kernel: |
| |
| Run dartanalyzer in strong mode: |
| ``` |
| (cd pkg/kernel && dartanalyzer --strong bin lib test) |
| ``` |
| |
| Run unit tests of kernel, front_end, and dart2js that are directly affected: |
| ``` |
| ./tools/test.py pkg/kernel -mrelease --checked |
| ./tools/test.py pkg/front_end -mrelease --checked |
| ./tools/test.py dart2js/kernel -mrelease --checked |
| ``` |
| |
| Run end-to-end tests using dartk + VM: |
| ``` |
| ./tools/test.py -m release -c dartk language |
| ``` |
| |
| Optionally (this is slow) run end-to-end tests using AOT: |
| ``` |
| ./tools/build.py dart_precompiled_runtime |
| ./tools/test.py -cdartkp -rdart_precompiled language co19 |
| ``` |
| |
| Comparing the output of compiling dart2js before and after the change. This [script][1] can make it easier to compare the results. |
