The Bechdel test is a test of female characterisation in movies. Passing the Bechdel test requires that:
- the movie [media] has at least two women characters;
- who talk to each other;
- about something other than a man.
Passing or failing the test is not an ironclad guarantee of well-rounded, feminist, characterisation but it is indicative of the problems of token women characters. A vast amount of geeky media fails the test.
The test has been applied to various media:
- tigtog applied it to a list of the “Most Significant SF & Fantasy Books of the Last 50 Years”, with few books meeting the full criteria at Larvatus Prodeo
- TV Tropes has the Deggans Rule
- Latoya Peterson has some drafts of a race version of the Bechdel test: racialicious.com
- Alaya Dawn Johnson posted the literal race version of the test and applied it to science fiction at The Angry Black Woman
- Ars Marginal posted a version that required: "a movie must have: at least one named character of color, whose primary trait is not their race, who does something important besides help a White person." 
- Lauredhel made a variant for children's toys, regarding whether there were two girls depicted in an advertisement and whether they were playing at being stereotypical women or not at Hoyden About Town
- Randall Munroe analyzed how many popular recent films had two female leads. Fugitivus analyzed the response to his post.
