    摘要: Methods and systems for improving performance in a virtualization environment. The method comprising: detecting, by a first software, a first set of features supported by a hardware device, wherein the first software runs on the hardware device; detecting a second set of features with which to run a second software, wherein the second software is launched by the first software with the second set of features; exposing one or more features in the second set of features to the second software, wherein the second software detects and enables the exposed features for a third software launched by the second software; and emulating a first feature without causing a trap such that control is transferred to the second software, in response to determining that the first feature is an exposed feature not included in the first set of features, wherein one or more sensitive events are associated with the first feature.

    摘要: A coverage analysis tool may determine coverage in respect to heterogeneous coverage tasks associated with different hierarchy levels of a tasks hierarchy. The coverage analysis tool may iteratively refine coverage tasks to determine coverage of sub-tasks. In some cases, coverage tasks may be unrefined in order to reduce overhead of coverage analysis in performance of the software under test, such that the software under test may perform in an essentially similar manner as in non-testing mode.

    摘要: Test plan to be utilized in a testing phase may be generated based on an initial test plan. A functional coverage model may be derived from the initial test plan. Modifications to the test plan may be automatically determined based on predetermined rules and parameters. Restrictions over possible combinations of values may be determined based on analysis of uncovered test activities in the initial test plan. Restrictions may be determined based on values of test activities in the initial test plan. Restrictions and modifications determined according to the disclosed subject matter may be indicated to a user for confirmation thereof.
