Enum TestRequirement 

pub enum TestRequirement {
    ExecutionEnvironment(ExecutionEnvironment),
    Vendor(Vendor),
    Isolation(IsolationType),
    RequiresCapability(&'static str),
    And(Box<TestRequirement>, Box<TestRequirement>),
    Or(Box<TestRequirement>, Box<TestRequirement>),
    Not(Box<TestRequirement>),
    Any,
}

A single requirement for a test to run.

Variants

ExecutionEnvironment(ExecutionEnvironment)

Execution environment requirement.

Vendor(Vendor)

Vendor requirement.

Isolation(IsolationType)

Isolation requirement.

RequiresCapability(&'static str)

Requires a named capability advertised by the execution environment or detected by petri.

Capabilities are how a test says “I need a specific resource to be provisioned for me” without naming who provides it or how. The execution environment can advertise capabilities via the comma-separated PETRI_CAPABILITIES environment variable, and petri can add capabilities that it detects itself. A test requiring a capability that is not available is skipped, so such tests automatically self-exclude on any host that cannot satisfy them.

And(Box<TestRequirement>, Box<TestRequirement>)

Logical AND of two requirements.

Or(Box<TestRequirement>, Box<TestRequirement>)

Logical OR of two requirements.

Not(Box<TestRequirement>)

Logical NOT of a requirement.

Any

Requirement satisfied by any host context.

Implementations

impl TestRequirement

pub fn and(self, other: TestRequirement) -> TestRequirement

Combine this requirement with another requirement using logical AND.

pub fn or(self, other: TestRequirement) -> TestRequirement

Combine this requirement with another requirement using logical OR.

pub fn not(self) -> TestRequirement

Negate this requirement.

pub fn is_satisfied(&self, context: &HostContext) -> bool

Evaluate if this requirement is satisfied with the given host context
