Request
The docstring for cpr:
cpr :Require|RunTests
This essentially means that it does:
(require 'my-test-ns :reload) (clojure.test/run-tests 'my-test-ns)
There's been a request to replicate this kind of functionality.
Evaluation
Benefits:
- Faster iteration workflow
Cons:
- May affect the user's built-up state / be unexpected behaviour
Prior art
CIDER: Doesn't do it
Approaches
(require :reload)
This reloads only the current namespace.
Issues
- Doesn't reload any transient dependencies
- Doesn't do multi-methods or protocols, due to their transient nature
- Deleted
deftest(and other things) will hang around - Hard to explain what does & doesn't update (unexpected behaviour)
Benefits
- Very simple
- For the case of updating a
deftest, only updates the minimum necessary
Simple refresh first
Issues
- Slower because it reloads all changed files
- May be unexpected that to run your tests, it reloads code on the other side of the project
- Bypasses the state management (the system), in the case of integrant, you could potentially break the
halt!multi-method - May remove temporary tests that have been
cppd, thrown in for quick test
Benefits
- The reload is very comprehensive, guaranteed to never leave a user scratching their head about why X didn't reload
Full refresh (including (reset))
Issues
- Slower because it reloads all changed files
- Slower because it
(reset)s - May be unexpected that to run your tests, it reloads code on the other side of the project
- Removes temporary tests that have been
cppd, thrown in for quick test
Benefits
- The reload is very comprehensive, guaranteed to never leave a user scratching their head about why X didn't reload
Do nothing
Benefits
- Least surprising behaviour
Issues
- More tedious when iterating on tests (mitigated by
cpaF?)
