|Part 3: Extending TestArchitect / Lesson #9: Creating Dashboard panels|
In this activity, you will create a heat map, which is a matrix in which the color, or shade, of each cell is used to represent a certain quantitative and/or qualitative value.
A heat map uses color and shading to help visualize an extra dimension on a chart or other graphic. In this exercise you will create a heat map that can be useful in alerting a test manager of a potential problem - the continuous failure of a given test module.
The heat map consists of a matrix with each unique test module placed along the vertical (y) axis, and with time along the horizontal (x) axis. The heat map tracks various test modules for a given AUT over the y-axis, with time ascending along the x-axis. Hence each cell represents a test performed at a given time, and is color-coded to indicate one of the three possible result outcomes. But a cell can be more than just red, yellow or green: contiguous Failed cells along a given row are colored in darker shades of red as they go from left to right. Hence, with a quick glance at the chart, the presence of any dark red cells alerts a test manager to the fact that one of more test modules have been failing continuously.
