Abstract

A tool for viewing data in a software environment is disclosed. The data may be a multi-dimensional data set. The viewer tool provides various features for viewing and exploring the data set. The viewer tool may be coupled to a test environment that generates data from the tests of a unit under test (UUT). The data may be generated from one or more sequences of tests that can be divided into batches. The viewer tool may receive the data from the test environment and analyze the data to provide a user with useful information on the data. The viewer tool may display the data with the information so that the user can obtain the information on the data. In particular, the viewer tool may enable the user to understand the relationship between the measured test data and the various test conditions under which the test data has been measured.

providing the graphical representation of the data for display via a user interface,

the user interface including one or more of;

a first portion for receiving the criteria,

a second portion identifying a parameter used to test the unit under test,

a third portion displaying a plot of the data in conjunction with the one or more of the variable or the parameter,

a fourth portion displaying one or more properties of the plot, or

a fifth portion displaying the data.

7. The method of claim 1, where providing the graphical representation of the portion of the data for display includes:

providing information identifying a distribution of the group of tests over the plurality of tests.

8. A device comprising:

one or more processors to;

receive data generated based on performing each test, of a plurality of tests, to test a unit under test in a test environment;

provide a graphical representation of the data for display;

receive, based on providing the graphical representation of the data for display, information identifying a variable associated with performing the plurality of tests and criteria for selecting a group of tests from the plurality of tests;

select the group of tests from the plurality of tests based on the criteria;

extract, based on selecting the group of tests, a portion of the data associated with the group of tests from the data;

modify the graphical representation of the data to generate a graphical representation of the portion of the data,

the graphical representation of the portion of the data, when displayed, depicting a relationship between the portion of the data and a test condition under which the variable had been evaluated for each test, of the group of tests; and

provide the graphical representation of the portion of the data for display.

9. The device of claim 8, where, when modifying the graphical representation of the data, the one or more processors are to:

link the graphical representation of the portion of the data to the group of tests.

10. The device of claim 8, where, when selecting the group of tests, the one or more processors are to:

exclude one or more tests from the plurality of tests based on the criteria.

11. The device of claim 8, where, when receiving the information identifying the variable and the criteria, the one or more processors are to:

receive information identifying a mathematical expression,

the mathematical expression defining the variable in terms of a group of other variables associated with testing the unit under test in the test environment.

12. The device of claim 8, where the one or more processors are further to:

provide information indicating a quantity of the plurality of tests not included in the group of tests.

13. The device of claim 8, where, when providing the graphical representation of the data for display, the one or more processors are to:

provide the graphical representation of the data for display via a user interface,

the user interface including two or more of;
