"""

|
|
Very minimal unittests for parts of the readline module.
|
||
|
|
|
||
|
|
These tests were added to check that the libedit emulation on OSX and
|
||
|
|
the "real" readline have the same interface for history manipulation. That's
|
||
|
|
why the tests cover only a small subset of the interface.
