Abstract: Disclosed are an active metal brazing paste composition, a brazing paste and a method for brazing ceramics and metals. The composition includes a binder and metal powder. The metal powder includes active metal brazing powder and brazing-aid metal powder. The brazing-aid metal powder contains copper powder and/or copper-silver alloy powder. The active metal brazing powder is alloy powder containing copper, silver, and an active metal. With the total weight of the metal powder as a reference, the content of the active metal is 1.5 wt % or more, the content of silver is 40 wt % to 90 wt %, and the content of oxygen is 0.5 wt % or less.

Abstract: A set of test cases is executed on a base code to produce a baseline result and on a changed code to produce a new result. From the baseline result and the new result, a first subset of tests cases is determined that are failing with the changed code but were not failing with the base code. A set of code blocks is determined in the changed code that includes those code blocks that are referenced by the first subset of test cases. A second subset is formed from the first subset by disregarding an unchanged code block that has remained unchanged from the base code to the changed code. A remaining code block is shortlisted for investigating based on a ranking of the remaining code block, which uses a number of test cases in the first subset of test cases that reference the remaining code block.
