manual functional testing based on project user stories
prioritize your tests so you can help the project the most - typically positive cases should be the first ones
be aware of your project allocation - if your allocation is not big enough, discuss it with your PM

reporting of your work
use X-Ray for test management - it must be clear what you tested and what was the results
use “light version” of test management - you don’t have to document every test step, simple description of what you will test is enough

reporting should be done every day
time should be reported to the correct user story or to administration task
