This is a LaTeX package that provides a command to produce dummy text interspersed with \index commands to test an index style or indexing application. The dummy text is mostly in English, but includes extended Latin characters provided either through LaTeX accent commands or directly with UTF-8 characters, depending on the setup, to allow for testing extended Latin alphabets. The supplementary package testidx-glossaries.sty uses the indexing interface provided by the glossaries package.
