Yes, she needs to take and pass an approved English test before she applies for a visa. Here's the latest document about that https://www.gov.uk/government/public...language-tests . You can search in the approved list for the Philippines to know where she can take it. Don't worry about the Life in the UK test yet. She'll have to do that when she's already here in the UK as a requirement for the future visa Indefinite Leave to Remain (ILR) and citizeship.

Also, I advise for her to take the B1 test because it will be the requirement for ILR in the future to save her retaking the English test.
