The Compare List operator compares lists to expected values in nested tables.

when test is⇓ story test fixture check test result nested lists check nested name elements apple id count subelements a 1 a b x y x z b 2 a b xx ZZ orange id c pear id count nested lists check nested name elements apple id count subelements a 1 a b x y x z b 2 a b xx ZZ orange id c pear id count

nested lists check nested name elements apple id count subelements a 1 a b x y x z b 2 a b xx ZZ orange id c pear id count

then result is

nested lists check nested name elements apple id count subelements a 1 a b x y x z b 2 a b xx ZZ orange id c pear id count

An empty actual list matches an empty expected cell.

when test is⇓ story test fixture check test result nested lists check nested name elements apple id count a 1 b 2 orange id c pear nested lists check nested name elements apple id count a 1 b 2 orange id c pear System.Collections.ArrayList

nested lists check nested name elements apple id count a 1 b 2 orange id c pear

then result is

nested lists check nested name elements apple id count a 1 b 2 orange id c pear System.Collections.ArrayList

An empty actual list matches an empty nested table in an expected cell.

when test is⇓ story test fixture check test result nested lists check nested name elements apple id count a 1 b 2 orange id c pear x nested lists check nested name elements apple id count a 1 b 2 orange id c pear x

nested lists check nested name elements apple id count a 1 b 2 orange id c pear x

then result is

nested lists check nested name elements apple id count a 1 b 2 orange id c pear x

Mismatches and errors are reported.

The report when an embedded table is missing isn't so good. But how to decide whether to put the List into a table? And what labels? And whether to include embedded tables to some depth?
