Examples of org.fest.assertions.error.MessageFormatter.format()

org.fest.assertions.error.MessageFormatter.format()

Interprets a printf-style format {@code String} for failed assertion messages. It is similar to {@link String#format(String,Object)}, except for:

the value of the given {@link Description} is used as the first argument referenced in the format string
each of the arguments in the given array is converted to a {@code String} by invoking {@link ToString#toStringOf(Object)}.

@param d the description of the failed assertion, may be {@code null}. @param format the format string. @param args arguments referenced by the format specifiers in the format string. @throws NullPointerException if the format string is {@code null}. @return A formatted {@code String}.
