assertPresent

public static int assertPresent(java.lang.String content,

                                java.lang.String... strings)

Convenience method for testing.

Parameters:

content - Piece of text to be scanned.

index1 - Index to scan from (inclusive).

index2 - Index to to scan unto (exclusive). If < 0 it is ignored.

strings - String that must be contained.

Returns:

Index of last string of strings.

Throws:

java.lang.IllegalArgumentException - if content does not contain any of the strings in the indicated substring.

                                    java.lang.String... strings)

Convenience method for testing. Opposite of assertPresent(String, int, int, String...).

Parameters:

content - Idem as at #assertPresent(String, int, int, String...).

index1 - Idem.

index2 - Index to to scan unto (exclusive).

strings - String that must not be contained.

Throws:

java.lang.IllegalArgumentException - if content does contain any of the strings in the indicated substring.
