When {msg} is omitted an error in the form "Expected False but
got {actual}" is produced.
*assert_match()*
assert_match({pattern}, {actual} [, {msg}])
When {pattern} does not match {actual} an error message is
added to |v:errors|.
{pattern} is used as with |=~|: The matching is always done
like 'magic' was set and 'cpoptions' is empty, no matter what
the actual value of 'magic' or 'cpoptions' is.
{actual} is used as a string, automatic conversion applies.
Use "^" and "$" to match with the start and end of the text.
Use both to match the whole text.
When {msg} is omitted an error in the form "Pattern {pattern}
does not match {actual}" is produced.
Example: >
assert_match('^f.*o$', 'foobar')
< Will result in a string to be added to |v:errors|:
test.vim line 12: Pattern '^f.*o$' does not match 'foobar' ~
assert_true({actual} [, {msg}]) *assert_true()*
When {actual} is not true an error message is added to
|v:errors|, like with |assert_equal()|.
