xUnit.net v1 XML Format

[!NOTE] This documentation for the v1 XML format is provided for historical purposes only. New transformations should use the XML Format v2, which is the XML format used for transformations by xUnit.net v2 and v3.

xUnit.net v1 exposed XML in several ways:

• As the native xUnit.net XML output;
• As the XML document used for output transformations;
• As the callback from Executor for version-resilient test runner authors.

The top level element of the document during transformation is the assembly element, and represents a single test assembly. During execution, the top level element will be the element currently being reported on.

<assembly>{ #assembly }

The assembly node contains information about the run of a test assembly. Transformations are handed a single assembly node as their XML document to transform against.

Attribute	Value
environment	The environment the tests were run in (32- vs. 64-bit and .NET version)
failed	The number of tests that failed
name	The fully qualified pathname of the assembly
passed	The number of tests that passed
run-date	The date the test run began
run-time	The time the test run began
skipped	The number of tests that were skipped
time	The time, in fractional seconds, spent running tests
total	The number of tests run

Child	Cardinality	Purpose
<class>	0..*	The classes run within the assembly

<class>{ #class }

The class node contains information about the tests run in a single test class. It also contains information about failures related to the class itself (i.e., during the creation or disposable of fixture data associated with IUseFixture<T>).

Attribute	Value
failed	The number of tests that failed
name	The full type name of the class
passed	The number of tests that passed
skipped	The number of tests that were skipped
time	The time, in fractional seconds, spent running tests
total	The number of tests run from the class

Child	Cardinality	Purpose
<failure>	0..1	Contains fixture related failure info
<test>	0..*	Contains the tests run within this class

<failure>{ #failure }

A failure node describes a failure of a class or test.

Attribute	Value
exception-type	The full type name of the exception that was thrown

Child	Cardinality	Purpose
<message>	1	The exception message
<stack-trace>	0..1	The stack trace of the exception

<reason>{ #reason }

A reason node contains information about why a test was skipped.

Child	Cardinality	Purpose
<message>	1	The reason the test was skipped

<start>{ #start }

The start node is only available via Executor, not for Transformations. It indicates that a test is about to start running, and can be used to update runner status to indicate such.

Attribute	Value
method	The name of the method
name	The display name of the test
type	The full type name of the class

<test>{ #test }

The test node contains information about a single test execution.

Attribute	Value
method	The name of the method
name	The display name of the test
result	One of Pass, Fail, or Skip
time	The time, in fractional seconds, spent running the test (not present for Skip results)
type	The full type name of the class

Child	Cardinality	Purpose
<failure>	0..1	Present if the test result is Fail
<output>	0..1	Contains any text was written to Console.Out or Console.Error
<reason>	0..1	Present if the test result is Skip
<traits>	0..1	Present if the test has any trait metadata

<trait>{ #trait }

The trait node contains information about a single name/value pair of metadata about a test.

Attribute	Value
name	The name of the trait
value	The value of the trait

<traits>{ #traits }

The traits node contains zero or more trait nodes which contain the metadata about a test.

Child	Cardinality	Purpose
<trait>	0..*	Nodes representing the traits of the test
