Test cases are executed by the software engineering test system. The test cases target software products. Test outputs are generated indicating whether the software engineering test system determined the test cases to have passed or failed. Separately, bug records are stored in a first dataset whose records identify corresponding bugs. Records of the test case executions are stored in a second dataset. Records thereof indicate whether a corresponding test case failed when executed. Such records may have bug identifiers entered by a test engineer and corresponding to bugs identified by the test engineer. The first dataset is parsed to identify records of test runs that have failed, and for each such test run record a bug identifier thereof is identified. Statistics such as failure counts are updated for the bugs found in the test run records.

Identifying high impact bugs

Techniques for calculating sub-pixel coverage values for text to be displayed, so as to enable caching of the sub-pixel coverage values. The sub-pixel coverage values may enable a linear combination of color information for the text with color information for one or more other, overlapping display elements for calculating composite color values to be used in controlling a display. Such composite color values to be used in controlling sub-pixels of a display may be calculated, in some embodiments, without performing a gamma correction process. Also described are techniques for retrieving cached sub-pixel coverage values and combining the values with color information for text and for other, overlapping display elements to calculate composite color values for sub-pixels of a display. At least one graphics processing unit (GPU) may be configured to perform operations using the sub-pixel coverage information and to calculate the composite color values for the sub-pixels.

Caching coverage values for rendering text using anti-aliasing techniques

Various embodiments enable automated testing of Application Program Interfaces (APIs) by abstracting API call signatures and processing the abstracted API call signatures utilizing one or more genetic algorithms. Utilizing the inventive approach, test cases are built and then analyzed using a genetic algorithm. This can be done to both identify problems, such as bugs, associated with the APIs, and/or to identify quality improvements.

Automated testing of application program interfaces using genetic algorithms

Methods and computer-readable media for displaying two-dimensional objects on a display device are disclosed. Rendering requests are received from an application to render two-dimensionally modeled graphics to a display device. Primitive geometries of drawing calls of the rendering requests are tessellated into sequences of triangles. The vertices of the triangles are mapped to a vertex buffer along with an index to identify associated constant data. Batching operations store and communicate calls and mapped data to a graphics processing unit by way of a three-dimensional rendering application program interface. Constant data associated with the mapped data are indexed and appended together in a constant buffer, thereby allowing drawing calls to be coalesced. A staging buffer and a staging texture are provided for batching text anti-aliasing operations. Shader fragments are precompiled and organized by way of a predetermined lookup table.
