been unsuccessful in buyingXFlow, because whether from profit orROIPoint of view, it is not optimal. However, profit-based strategies cannot distinguish between a and B traffic ( they have the same profit ), so separately purchased 1M of traffic from a and B. ROI -based strategies ignore traffic from a , just like ignoring X, and focus only on high roi Type B traffic. Therefore, the ROI-based strategy will have a lower CPA than the profit-based strategy .

Black-Box testing is also called functional testing or data-driven testing
-The test object as the invisible inside the black box, without considering the internal structure of the program and the process of the case, the tester only according to the requirements of the program functional specifications to determine th

The loop body is executed within the boundaries of the loop and the boundary of the operation.4. test the validity of internal data structures. Black-

So the black box test is actually checking to see if the following requirements are met:
1, C correctness (correctness): The results of the calculation, naming and so on.
2, D availability (usability): Whether it can meet the requirements of the software description.
3, E boundar
1.Black box testingThe black box test is also called a function test or data-driven test. It is a function of a known product. It is tested to check whether each function can be used normally.ProgramAs a dark basin that cannot be opened, the tester tests the program interface without considering the internal structure
also testing those that are illegal but possible.
The methods of designing test cases using black box technology are: Equivalence class division, boundary value analysis, error inference, causality diagram and comprehensive strategy.
Black-Box testing focuses on the functional requirements of testing software, or
black box testing. I thought a long time ago, hackers are through black box testing methods to find security vulnerabilities, how can we say that black box testing technology is low? With their level to the hacker's direction clo
Software testing methods are generally divided into two kinds: white box test and black box test. White box testing, also known as structural testing, logic-driven testing, or testing based on the program itself, focuses on the internal structure and algorithms of the program, often without concern for functional and p
able to find out that the program violates the design specification, that is, the program itself is a wrong program. Second, the exhaustive path test cannot detect errors in the program due to missing paths. Third, the exhaustive path test may not find some data-related errors.

Obviously, if the external features themselves have problems or specifications are wrong, the use of ink cartridges test method is not found. The black box test is mainly to find the following types of errors:1. Are there any features that are incorrect or missing?2, on the interface, the input
