Have had/did have

[diplomacy]

The test is going well. We haven't had any problem.

Why do we use "haven't had" instead of "didn't have"?

could you please clear it out straightaway.

Because the test is ongoing.

As bhai said, the first sentence makes it clear that the test is still underway. If it helps, imagine that it reads "We haven't had any problems yet" or "We haven't had any problems so far".

If it started "The test went well", showing that the test is over, it could be followed by "We didn't have any problems".

Please don't ask us to reply "straight away" (note though, that it is written as two words). We are all volunteers. We will get to your post as and when we have the time.

...and we won't clear it out; we'll clear it up.

I have a confusion about "had" in these sentences. We haven't had any problems yet or We haven't had any problems so far.
Why do we use "had" here? As per my limited knowledge about grammar "had" is used only as follows
1, Past tense i.e. Smith had gone to New York last month. 2, Used for past possession i.e. Smith had a BMW when he lived in New York. 3, Used in conditional sentences i.e. If Jadoon had money he would visit Sydney at the eve of new year. Or if Jadoon had had money he would have visited Sydney at the eve of new year. Please teach me more uses of "Had" to clear my confusion.
Thank you very much

It is the third form (past participle) of the verb HAVE, used in the construction of perfect and passive forms.

Would you have been less confused if it had read "We haven't experienced any problems yet"?
