Test Case Variations

---

V-01 Returns correct measure for unit-squareMiles

Documentation

Tests that element returned is unit for specified item.

Inputs

• schema: unit-test-concepts.xsd
• instance: unit-test-instance.xml (DTS Discovery starting point) (ID=V01)
• Function Call: xfi:unit-numerator( xfi:unit( /xbrli:xbrl/c:a[1] ) )
  
  (against file V01)

Outputs

• Result test: $result instance of element(xbrli:measure)+ and count( $result ) eq 1 and $result is //xbrli:unit[@id eq 'unit-squareMiles']/xbrli:measure

---

V-02 Returns correct measures for multi-measure unit

Documentation

Tests that elements returned are measures for specified item.

Inputs

• schema: unit-test-concepts.xsd
• instance: unit-test-instance.xml (DTS Discovery starting point) (ID=V02)
• Function Call: xfi:unit-numerator( //xbrli:unit[@id eq 'unit-power'] )
  
  (against file V02)

Outputs

• Result test: $result instance of element(xbrli:measure)+ and count( $result intersect ( //xbrli:unit[@id eq 'unit-power']/xbrli:measure[1], //xbrli:unit[@id eq 'unit-power']/xbrli:measure[2] ) ) eq 2

---

V-03 Returns measure for divide based unit

Documentation

Inputs

• schema: unit-test-concepts.xsd

• Function Call: xfi:unit-numerator( //xbrli:unit[@id eq 'unit-energy'] )
  
  (against file V03)

Outputs

• Result test: $result instance of element(xbrli:measure)+ and count( $result ) eq 3 and count( $result[local-name() eq 'measure' and local-name-from-QName(.) eq 'meters'] ) eq 2 and count( $result[local-name() eq 'measure' and local-name-from-QName(.) eq 'kilogram'] ) eq 1

---

V-04 Returns measure for inverse unit (1/secs)

Documentation
