|
|
|
+ ./lisp/test-*.el, "M-x eval-buffer RET", "M-x ert RET t RET"
|
|
|
+
|
|
|
+ Consider to set pp-escape-newlines nil before running the test when
|
|
|
+ looking at "should" in the ERT results buffer. Especially when
|
|
|
+ using "l" to look at passed test results and possibly missing an
|
|
|
+ appropriate setting of pp-escape-newlines made only temporarily for
|
|
|
+ the running time of the test as e. g. tests using

|
