Method Details

messageFor

static String messageFor(String message,
 CharSequence expected,
 CharSequence actual)

Returns a message appropriate for string comparisons. TODO(user): Do something closer to what JUnit's ComparisonFailure does.

format

static String format(String template,
 Object... args)

Substitutes each %s in template with an argument. These are matched by position - the first %s gets args[0], etc. If there are more arguments than placeholders, the unmatched arguments will be appended to the end of the formatted message in square braces. Cribbed from Guava's Preconditions to allow for a GWT-compatible alternative to String.format(String, Object...)

Parameters:

template - a non-null string containing 0 or more %s placeholders.

args - the arguments to be substituted into the message template. Arguments are converted to strings using String.valueOf(Object). Arguments can be null.
