TestProcess class
A wrapper for Process that provides a convenient API for testing its standard IO and interacting with it from a test.
If the test fails, this will automatically print out any stdout and stderr from the process to aid debugging.
This may be extended to provide custom implementations of stdoutStream and stderrStream. These will automatically be picked up by the stdout and stderr queues, but the debug log will still contain the original output.
Constructors
- TestProcess(Process process, String description, {Encoding encoding = utf8, bool forwardStdio = false})
-
Creates a TestProcess for
process.
Properties
- description → String
-
A human-friendly description of this process.
final

exitCode
→ Future<
int> -
Returns a Future which completes to the exit code of the process, once
it completes.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- pid → int
-
The process ID of the process.
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.

StreamQueuethat emits each line of stdout from the process.latefinal
Methods
-
kill(
) → Future< void> - Kills the process (with SIGKILL on POSIX operating systems), and returns a future that completes once it's dead.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
shouldExit(
[Object? expectedExitCode]) → Future< void> -
Waits for the process to exit, and verifies that the exit code matches
expectedExitCode(if given). -
signal(
ProcessSignal signal) → void - Sends signal to the process.
-
stderrStream(
) → Stream< String> - Returns a copy of stderr as a single-subscriber stream.
-
stdoutStream(
) → Stream< String> - Returns a copy of stdout as a single-subscriber stream.
-
toString(
) → String -
A string representation of this object.

Operators

operator ==(
Object other) → bool -
The equality operator.
