Test Case Variations

---

V-01 Returns no measure for denominator-less 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-denominator( xfi:unit( /xbrli:xbrl/c:a[1] ) )
  
  (against file V01)

Outputs

• Result test: empty( $result )

---

V-02 Returns correct measures for single-divisor 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-denominator( //xbrli:unit[@id eq 'unit-speedKMH'] )
  
  (against file V02)

Outputs

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

---

V-03 Returns measure for divide based unit

Documentation

Inputs

• schema: unit-test-concepts.xsd
• instance: unit-test-instance.xml (DTS Discovery starting point) (ID=V03)
• Function Call: xfi:unit-denominator( //xbrli:unit[@id eq 'unit-energy'] )
  
  (against file V03)

Outputs

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

---

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

Documentation

Inputs

• schema: unit-test-concepts.xsd
• instance: unit-test-instance.xml (DTS Discovery starting point) (ID=V04)
• Function Call: xfi:unit-denominator( //xbrli:unit[@id eq 'unit-inverse-time'] )
  
  (against file V04)

Outputs

• Result test: $result instance of element(xbrli:measure)* and count( $result ) eq 1 and $result eq QName('http://xbrl.org/formula/conformance/example', 'concept:seconds')

---

V-06 A sequence of items as argument

Documentation

XPath-defined error for node type incorrect arity of arguments.

Inputs

• schema: unit-test-concepts.xsd
• instance: unit-test-instance.xml (DTS Discovery starting point) (ID=V06)
• Function Call: xfi:unit-denominator( //xbrli:unit[starts-with(@id,'unit-speed')] )
  
  (against file V06)

Outputs

• Error code: xqt-err:XPTY0004

---

V-07 Wrong number of arguments to function

Documentation

XPath-defined error for node type incorrect number of arguments.

Inputs

• schema: unit-test-concepts.xsd
• instance: unit-test-instance.xml (DTS Discovery starting point) (ID=V07)
• Function Call: xfi:unit-denominator( //xbrli:unit[@id eq 'unit-speedMPH'], //xbrli:unit[@id eq 'unit-speedKMH'] )
  
  (against file V07)

Outputs

• Error code: xqt-err:XPST0017
