assertPresent

public static int assertPresent(String content,
                                int index1,
                                int index2,
                                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:

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

assertNotPresent

public static void assertNotPresent(String content,
                                    int index1,
                                    int index2,
                                    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:

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