@Target({TYPE,METHOD}) @Retention(RUNTIME) @Documented @Inherited @API(status=STABLE, since="5.7") public @interface Timeout
@Timeout
is used to define a timeout for a method or all testable methods within one class and its@Nested
classes.This annotation may also be used on lifecycle methods annotated with
@BeforeAll
,@BeforeEach
,@AfterEach
, or@AfterAll
.Applying this annotation to a test class has the same effect as applying it to all testable methods, i.e. all methods annotated or meta-annotated with
@Test
,@TestFactory
, or@TestTemplate
, but not to its lifecycle methods.Default Timeouts
If this annotation is not present, no timeout will be used unless a default timeout is defined via one of the following configuration parameters:
junit.jupiter.execution.timeout.default
- Default timeout for all testable and lifecycle methods
junit.jupiter.execution.timeout.testable.method.default
- Default timeout for all testable methods
junit.jupiter.execution.timeout.test.method.default
- Default timeout for
@Test
methods junit.jupiter.execution.timeout.testtemplate.method.default
- Default timeout for
@TestTemplate
methods junit.jupiter.execution.timeout.testfactory.method.default
- Default timeout for
@TestFactory
methods junit.jupiter.execution.timeout.lifecycle.method.default
- Default timeout for all lifecycle methods
junit.jupiter.execution.timeout.beforeall.method.default
- Default timeout for
@BeforeAll
methods junit.jupiter.execution.timeout.beforeeach.method.default
- Default timeout for
@BeforeEach
methods junit.jupiter.execution.timeout.aftereach.method.default
- Default timeout for
@AfterEach
methods junit.jupiter.execution.timeout.afterall.method.default
- Default timeout for
@AfterAll
methods
More specific configuration parameters override less specific ones. For example,
junit.jupiter.execution.timeout.test.method.default
overridesjunit.jupiter.execution.timeout.testable.method.default
which overridesjunit.jupiter.execution.timeout.default
.Values must be in the following, case-insensitive format:
<number> [ns|μs|ms|s|m|h|d]
. The space between the number and the unit may be omitted. Specifying no unit is equivalent to using seconds.Value Equivalent annotation 42
