| # 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 runtime_precompiled | |
| ./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. | |
