Feature: Validation pipeline _ThreadLocalStream coverage
|
|
As a developer maintaining the validation pipeline
|
|
I want to exercise the _ThreadLocalStream helper methods
|
|
So that all stream-interface methods have coverage
|
|
|
|
Background:
|
|
Given a thread-local stream wrapping a mock original stream
|
|
|
|
# --- encoding property ---------------------------------------------------
|
|
|
|
Scenario: encoding property returns the original stream encoding
|
|
Given the original stream has encoding "utf-8"
|
|
When I read the thread-local stream encoding
|
|
Then the encoding should be "utf-8"
|
|
|
|
Scenario: encoding property falls back to utf-8 when original has no encoding
|
|
Given the original stream has no encoding attribute
|
|
When I read the thread-local stream encoding
|
|
Then the encoding should be "utf-8"
|
|
|
|
# --- writable method -----------------------------------------------------
|
|
|
|
Scenario: writable returns True
|
|
When I check if the thread-local stream is writable
|
|
Then writable should return True
|
|
|
|
# --- readable method -----------------------------------------------------
|
|
|
|
Scenario: readable returns False
|
|
When I check if the thread-local stream is readable
|
|
Then readable should return False
|
|
|
|
# --- flush method with active buffer -------------------------------------
|
|
|
|
Scenario: flush flushes the capture buffer when capturing is active
|
|
Given capture is started on the thread-local stream
|
|
When I write "hello" to the thread-local stream
|
|
And I flush the thread-local stream
|
|
Then the flush should succeed without error
|
|
|
|
# --- flush method without active buffer ----------------------------------
|
|
|
|
Scenario: flush flushes the original stream when no capture is active
|
|
When I flush the thread-local stream
|
|
Then the original stream flush should be called
|
|
|
|
# --- isatty method -------------------------------------------------------
|
|
|
|
Scenario: isatty delegates to the original stream
|
|
Given the original stream isatty returns True
|
|
When I check if the thread-local stream isatty
|
|
Then isatty should return True
|
|
|
|
Scenario: isatty returns False when original returns False
|
|
Given the original stream isatty returns False
|
|
When I check if the thread-local stream isatty
|
|
Then isatty should return False
|
|
|
|
# --- write with and without capture ------------------------------------
|
|
|
|
Scenario: write without capture goes to original stream
|
|
When I write "direct output" to the thread-local stream
|
|
Then the original stream should have received "direct output"
|
|
|
|
Scenario: write with capture goes to capture buffer
|
|
Given capture is started on the thread-local stream
|
|
When I write "captured output" to the thread-local stream
|
|
And capture is stopped on the thread-local stream
|
|
Then the captured text should be "captured output"
|
|
|
|
# --- stop_capture when no capture was started ----------------------------
|
|
|
|
Scenario: stop_capture returns empty string when no capture was started
|
|
When capture is stopped on the thread-local stream
|
|
Then the captured text should be empty
|
