**Estimated Time Of Arrival Test Cases**

Well, a low-level test case not possible to write based on just one line. But I can try for high-level scenarios which you can use to write a test case.

Assumption: estimated time of arrival for shipment/order But still, you have to design scenarios around Calculation, Like,

- Total time should be an inclusion of estimated time to complete all the mid-phases like shipping, packing, etc.
- Also, we need to take care where one of the phases exceeds the time, total time should get change accordingly.
- If the shipment is not on the track like all or the initial phase itself exceeded the estimated time, it needs to show delay notification.
- There should be some failover strategy to identify if the estimation is exceeded.
- Acknowledgment once shipment arrived.
- Tracking information like in page tracking by fetching real-time updates from courier partners.
- If provided: notification updates like email, SMS, or app notification.

### What is ETA?

Before discussing what ETA is, let’s try to know the full form of ETA. ETA stands for the estimated time of arrival.

#### Example

In our everyday life in most of our time, we are calculating the estimated time of arrival. for example, sometimes we inform our friend like I will be there in 10 minutes. Or I want to start from your house so that you can reach the cinema hall or theatre in time so that you will not miss the previews.

### What is the estimated time of arrival formula?

When we are going to calculate the ETA we have to consider three elements the distance speed and time.

**Distance:**this is the distance of where we are and where we plan to go. For calculating the distance we have different measurement units.**Speed:**this decides how fast you want to travel from one point to your destination point.**Time:**this is what we need to solve. in every situation, we know the distance and speed.

**Estimated Time of Arrival Formula**

- Distance = Speed x Time
- Speed = Distance/Time
- Time = Distance/Speed
