Should you write your research report in future, past or present tense?
Some parts of the report can be written before you have conducted the research itself, such as Background and Methods. It can be tempting to write in future tense (e.g. "The tools will be tested by creating a simple pong game with each of them."). Keep in mind, however, that when the reader reads your report, your research will be finished! As a general guideline, write your report in the past tense ("The tools were tested") or present perfect ("The tools have been tested"). Similarly, when describing research done by others, this has been done in the past.
For facts and findings that still hold true, you shift to present tense ("The tools are free to use." or "Playtesting improves the quality of the end product (Blizzard, 2020).").
