Test Case Variations

---

V-01 xfi:period-start returns correct dateTime for an instant context

Documentation

Tests that either a the instant dateTime element is provided, or an equivalent atomic value of expected dateTime

Inputs

• schema: period-start-tests.xsd
• instance: hello-worlds-instance.xml (DTS Discovery starting point) (ID=V01)
• Function Call: xfi:period-start( /xbrli:xbrl/xbrli:context[@id eq 'context-earth']/xbrli:period )
  
  (against file V01)

Outputs

• Result test: ($result instance of element(*,xs:dateTime) or $result instance of xs:dateTime) and count( $result ) eq 1 and $result eq xs:dateTime("2007-12-31T24:00:00")

  (against file V02)

Outputs

• Result test: ($result instance of element(*,xs:dateTime) or $result instance of xs:dateTime) and count( $result ) eq 1 and $result eq xs:dateTime("2007-12-31T24:00:00")
