# error(msg): report an error in Go's test framework without halting execution.

# This is distinct from the built-in fail function, which halts execution.
|

|
|
# catch(f): evaluate f() and returns its evaluation error message, if any
|

|
|
# matches(str, pattern): report whether str matches regular expression pattern.
|

|
|
# module(**kwargs): a constructor for a module.

# _freeze(x): freeze the value x and everything reachable from it.
|
||
|
|
#
|
||
|
|
# Clients may use these functions to define their own testing abstractions.
