Struct zebra_test::command::TestOutput

pub struct TestOutput<T> {
    pub dir: Option<T>,
    pub cmd: String,
    pub output: Output,
}

Test command output logs.

Fields

dir: Option<T>

The test directory for this test output.

Keeps the test dir around from TestChild, so it doesn’t get deleted during wait_with_output.

cmd: String

The test command for this test output.

output: Output

The test exit status, standard out, and standard error.

Implementations

impl<T> TestOutput<T>

pub fn assert_success(self) -> Result<Self>

pub fn assert_failure(self) -> Result<Self>

pub fn output_check<P>( &self, output_predicate: P, output: &[u8], output_name: impl ToString + Debug, err_msg: impl ToString + Debug, ) -> Result<&Self>

where P: FnOnce(&str) -> bool,

Checks the output of a command, using a closure to determine if the output is valid.

If the closure returns true, the check returns Ok(self). If the closure returns false, the check returns an error containing output_name and err_msg, with context from the command.

output is typically self.output.stdout or self.output.stderr.

pub fn any_output_line<P>( &self, line_predicate: P, output: &[u8], output_name: impl ToString + Debug, err_msg: impl ToString + Debug, ) -> Result<&Self>

where P: FnMut(&str) -> bool,

Checks each line in the output of a command, using a closure to determine if the line is valid.

See Self::output_check for details.

pub fn any_output_line_contains( &self, s: &str, output: &[u8], output_name: impl ToString + Debug, err_msg: impl ToString + Debug, ) -> Result<&Self>

Tests if any lines in the output of a command contain s.

See Self::any_output_line for details.

pub fn stdout_contains(&self, s: &str) -> Result<&Self>

Tests if standard output contains s.

pub fn stdout_matches<R>(&self, regex: R) -> Result<&Self>

where R: ToRegexSet + Debug,

Tests if standard output matches regex.

pub fn stdout_line_contains(&self, s: &str) -> Result<&Self>

Tests if any lines in standard output contain s.

pub fn stdout_line_matches<R>(&self, regex: R) -> Result<&Self>

where R: ToRegexSet + Debug,

Tests if any lines in standard output match regex.

pub fn stderr_contains(&self, s: &str) -> Result<&Self>

Tests if standard error contains s.

pub fn stderr_matches<R>(&self, regex: R) -> Result<&Self>

where R: ToRegexSet + Debug,

Tests if standard error matches regex.

pub fn stderr_line_contains(&self, s: &str) -> Result<&Self>

Tests if any lines in standard error contain s.

pub fn stderr_line_matches<R>(&self, regex: R) -> Result<&Self>

where R: ToRegexSet + Debug,

Tests if any lines in standard error match regex.

pub fn assert_was_killed(&self) -> Result<()>

Returns Ok if the program was killed, Err(Report) if exit was by another reason.

pub fn assert_was_not_killed(&self) -> Result<()>

Returns Ok if the program was not killed, Err(Report) if exit was by another reason.

fn was_killed(&self) -> bool

pub fn take_dir(&mut self) -> Option<T>

Takes the generic dir parameter out of this TestOutput.
