FE quality control

In software development, which of the following is an appropriate explanation of a test that uses stubs?

• During the execution of a program, the contents of a variable or register are displayed as required, and the test is continued after the contents are modified if necessary.

• Each time a specific instruction is executed, the contents of registers and main memory are dumped to check whether the process is executed correctly.

• When a top-down test is performed, a dummy lower-level module that is called by the upper-level module is prepared to stand in for an unfinished portion of the program.

• When a unit test for a module is performed, a dummy higher-level module that calls the module is prepared to check whether the operation is executed correctly.

Which of the following is a chart or a diagram that is used to analyze possible relationships between two variables and is composed of a horizontal axis containing the measured values of one variable and a vertical axis representing the measurements of the other variable?

• Cause-and-effect diagram

• Control chart

• Pareto chart

• Scatter diagram

Among the different types of software tests, which of the following is a test that is performed with the purpose of checking whether or not a location that must not be affected by changes made for software maintenance is affected?

• Integration test

• Operational test

• Regression test

• System test

Test data about the part of a program shown in the flowchart below is specified by decision condition coverage (branch coverage). When this test data is changed to being specified by multiple-condition coverage, which of the following is the appropriate test data to be added? Here, the part enclosed by parentheses () represents the set of test data.

The flow of code:

P1;

if (A > 6 or B = 0) then P2;

Current test data:

Test data by decision condition coverage (branch coverage)

(A = 4, B = 1), (A = 5, B = 0)

• (A = 3, B = 0), (A = 7, B = 2)

• (A = 3, B = 2), (A = 8, B = 0)

• (A = 4, B = 0), (A = 8, B = 0)

• (A = 7, B = 0), (A = 8, B = 2)

In the flowchart below, what is the minimum number of test cases that satisfies the decision condition coverage (branch coverage)?

• 1

• 2

• 3

• 4

The integration test for software composed of modules arranged in a hierarchical structure is performed from a high-level module. In such a case, which of the following is a test module that is used as a substitute for a low-level module?

• Driver

• Emulator

• Simulator

• Stub

Which of the following is an appropriate description concerning test data for the black box testing?

• Test data is created based on branch coverage.

• Test data is created based on condition coverage.

• Test data is created based on external specification.

• Test data is created based on program structure.

When a software component is tested, which of the following is an appropriate combination of X and Y?

X: It calls the software component to be tested.

Y: It is called from the software component to be tested.

• X: Component

  Y: Unit

• X: Driver

  Y: Stub

• X: Stub

  Y: Driver

• X: Unit

  Y: Component
