Vertical Bar Chart – Component test plan
Sub-components: Bar, Line, Legends, Callout, Labels
- Bar: bar data, bar color (single/multi colors), bar label (show/hide)
- Line: show/hide line, highlight data point on line and show callout
- Legends: show/hide legends, highlight the corresponding bar/line on legend hover
- Callout: Default/custom callout
- Labels: x-Axis labels default/rotated
| Test steps | Validation | Tool used |
|---|---|---|
| Test 1: [Snapshot testing] | ||
| - With only data prop, numerical data on x-axis. | Renders vertical bar chart correctly | Enzyme |
| - With only data prop, string data on x-axis. | Renders vertical bar chart correctly | RTL |
| - With HideLegend prop set to “true” | Should hide legends | Enzyme |
| - With HideTooltip prop set to “true” | Should hide the tooltip in chart | Enzyme |
| - With EnabledLegendsWrapLines set to “true” | Should enable the legends to wrap lines if there is not enough space to show all legends on a single line | Enzyme |
| - With ShowXAxisLablesTooltip set to “true” | Should truncate x axis labels and show tooltip on x axis labels | Enzyme |
| - With WrapXAxisLables set to “true” | Should wrap x axis label values | Enzyme |
| - With yAxisTickFormat set to “%d” | Should render the y-axis ticks in the format specified | Enzyme |
| - With HideLabels set to “true” | Should hide the bar labels | Enzyme |
| Test 2: Basic props testing | ||
| - HideLegend prop set to “false” | Should mount legend when hideLegend is false | Enzyme |
| - HideTooltip prop set to “false” | Should mount callout when hideTootip is false | Enzyme |
| - onRenderCalloutPerStack prop is not given | Should not render onRenderCalloutPerStack | Enzyme |
| - onRenderCalloutPerDataPoint is given | Should render onRenderCalloutPerDataPoint | Enzyme |
| - onRenderCalloutPerDataPoint is not given | Should not render onRenderCalloutPerDataPoint | Enzyme |
| Test 3: Render calling with respective to props | ||
| - No prop changes: Mount vertical bar chart and then set the same props again | Render function should have been called twice | Enzyme |
| - Prop changes: Mount vertical bar chart and then set the some other prop | Render function should have been called twice | Enzyme |
| Test 4: Mouse events | ||
| - Mouse over on a bar | Should render callout correctly on mouseover | Enzyme |
| - Mouse over on a bar with customized callout | Should render customized callout on mouseover | Enzyme |
| Test 5: Render empty chart aria label div when chart is empty | ||
| - Vertical bar chart mounted with non-empty data | No empty chart aria label div rendered | Enzyme |
| - Vertical bar chart mounted with empty data | Empty chart aria label div rendered | Enzyme |
| Test 6: Render empty chart calling with respective to props | ||
| - prop changes: Mount vertical bar chart with empty data and then set the props | Render function should have been called 3 times | Enzyme |
| Test 7: [Sub-Component]: Vertical Bar | ||
| - Specify bar width | Should render the bar with the given width | RTL |
| - Specify bar colors (multiple) | Should render the bars with the specified colors | RTL |
| - Specify to use a single color for all bars | Should render the bars with the single specified color | RTL |
| - Hide the bar labels | Should render the bars with labels hidden | RTL |
| - Provide xAxisPadding between the bars | Should render the bars with the given padding between bar's or lines in the graph | E2E |
| - Localize the numbers of the bars with a given culture | Should render the bars with the numbers localized in the given culture | E2E |
| Test 8: [Sub-Component]: Line | ||
| - Specify line data | Should render line with the data provided | RTL |
| - Hover mouse over the data points | Should highlight the data points (No callout is rendered when we hover only on the line. Callout appears on hover over the bars only.) | RTL |
| Test 9: [Sub-Component]: Legends | ||
| - Hide legends | Should not show any rendered legends | RTL |
| - Hover mouse over bar legends | Should reduce the opacity of the other bars/lines and their legends | RTL |
| - Hover mouse over line legends | Should reduce the opacity of the other bars/lines and their legends | RTL |
| Test 10: [Sub-Component]: Callout | ||
| - Hover mouse over a bar | Should call the handler on mouse over bar | RTL |
| - Hover mouse over a bar | Should show the default callout over that bar | RTL |
| - Specify custom callout and hover mouse over a bar | Should show the custom callout over that bar | RTL |
| - Specify custom callout and hover mouse over the line | Should not show the custom callout over that line as custom callout is rendered only on mouse over on the bars. | RTL |
| Test 11: [Sub-Component]: x-axis labels | ||
| - Truncate x-axis labels | Should show the x-axis labels tooltip when hovered | RTL |
| - Rotate x-axis labels | Should rotate the x-axis labels by 45 degrees | RTL |
| Test 12: [Sub-Component]: Screen resolution | ||
| - Increase the screen resolution (zoom in) | Should remain unchanged on zoom in | RTL |
| - Decrease the screen resolution (zoom out) | Should remain unchanged on zoom out | RTL |
| Test 13: Theme changed to Dark Theme | Should reflect theme change | RTL |
