Abstract: The present disclosure provides a gene combination for expressing and producing terrequinone A in Escherichia coli and use thereof. The gene combination includes a tdiAS gene, a tdiBS gene, a tdiCS gene, a tdiDS gene, a tdiES gene, an sfpS gene, an ScCKS gene, and an AtIPKS gene with nucleotide sequences set forth in SEQ ID NOS:1 to 8. In the present disclosure, a recombinant engineered strain capable of producing terrequinone A having anti-cancer activity is obtained by separately constructing recombinant plasmids pC02 and pU03 through the eight genes and transforming the two recombinant plasmids into E. coli. The content of terrequinone A in a fermentation broth thereof is 106.3 mg/L, which has potential application value in the biopharmaceutical field.

Abstract: A method and device for executing test cases includes obtaining a set of test cases to be executed, and determining a test platform type and a test script associated with each test case in the set of test cases based on a knowledge base. The set of test cases may be divided into a plurality of test subsets or test suites based on the test platform type, and test cases in each test subset executed using the respective test environment and test script. The test suites may be generated automatically based on the knowledge base, and the respective test environment and test script are used for executing each test suite. Automatic generation and execution of the test suites can improve the operation efficiency for test cases.

Abstract: A method, device, and computer program product for testing code. The method includes identifying a plurality of test points in the code and a plurality of test values to be assigned to the plurality of test points. At least one of the plurality of test points is to be assigned with two or more test values. The method also includes comparing a target test case with a set of test cases. The target test case and the set of test cases are associated with the plurality of test points. The method further includes, in response to determining that each of combinations of the test values assigned to at least two of the plurality of test points in the target test case is present in the set of test cases, excluding the target test case from the set of test cases.
