and(): decide whether a release can ship

Medium

A build pipeline runs several test suites and reports the number of failures in each, plus the code coverage as a percentage.

Return true when the release can ship: every suite has 0 failures and coverage is at least 80.

Watch out

  • A comparison against a list gives one Boolean per suite, and and() accepts those alongside its other arguments.
  • and() reads an empty list as true, since nothing failed, but a release that was never tested must not ship.

Inputs

  • ri!failures: List of Integer, one count per suite
  • ri!coverage: Integer

ri! Rule Inputs

ri!failuresList of Integer
{
  0,

Example 1: All green

Input: ri!failures
{
  0,
  0,
  0
}
Input: ri!coverage
85
Output:
true

Example 2: One suite failing

Input: ri!failures
{
  0,
  2,
  0
}
Input: ri!coverage
90
Output:
false

Example 3: Coverage just short

Input: ri!failures
{
  0,
  0
}
Input: ri!coverage
79
Output:
false

Example 4: Coverage exactly 80

Input: ri!failures
{0}
Input: ri!coverage
80
Output:
true

Example 5: No suites ran

Input: ri!failures
{}
Input: ri!coverage
95
Output:
false

Appian Expression Tips

  • • Use ri!variableName for rule inputs
  • • Use a!localVariables(local!x: …, body) for locals
  • • Use a!forEach(items: …, expression: fv!item) to iterate
  • • Use where() / reject(fn!isnull, list) to filter
