Unit test plan for Donut Chart
This test plan contains the list of unit testable functions which are used as a part of the Donut Chart component.
Identify the functions that can be unit tested (example, functions having calculations or getting values from Utils, etc).
- If required, extract the unit testable portions out of the functions which can be independently unit tested without any requirement of DOM elements.
- Alternatively, mock the sections that cannot be unit tested.
| Functions | Can it be unit tested | Reason |
|---|---|---|
a. convertToLocaleString() | Yes | |
b.getAccessibleDataObject() | Yes | |
c. _valueInsideDonut() | No | private function which can only be tested by rendering the donut chart component. |
d. wrapTextInsideDonut() | No | cannot be unit tested as it requires the tspan length to be calculated using Browser Functions like getComputedTextLength(). |
e. _computeTotalValue() | No | depends on the data prop passed down from the DonutChart.base to Pie during component rendering. Also since this is a private function, it can only be tested via component rendering. |
