The first thing to understand is that the Java for unit testing and integration testing in MAVEN is mixed, without a default directory. You need to configure which time unit tests and which are integration tests yourself.
Default does not run, only installs the Surfire plug-in only then runs the single test, only installs the Failuresafe to run the test directory under the IT end class. The default is to identify JUnit and so on.

coverage testing in the Golang
Golang provides a number of tool chains that can be used to facilitate unit testing, analyze performance bottlenecks, provide runtime information, and so on, all of which are useful.
Go test This tool people should use more, I used to do mostly for unit testing, go to do unit testing is very convenient, but I ignored the coverage test.
How much code does the unit test cover?
commands:
Gradlew Test/connectedandroidtest
These two commands are to execute (unit) the test and generate a report, and then a similar command if you want to test code coverage:
Gradlew Createdebugcoveragereport
Then error:Well, the tutorial is to run this command, dead or alive error, OK, only x wall to ask Google, and then found that this command is in the JACOCO framework itself, not the testers themselves defined, and then invoke the command:G
The previous article describes how to let Surefire,failsafe and Jacoco maven plugin How to combine configuration, this article specifically explains how to use the Powermock agent to solve coverage incompatibility problems.First add Powermock agent maven dependency in POM
Note:it ' s recommended that's put powermock-module-junit4-rule-agent before JUnit in the classpath. (Remember to put this dependency before JUnit).
Next, modify the previous test
, the number of times to restart the machine can be minimized.The task is to calculate the minimum number of times. Initially, both machines are running in mode No. 0.Ideas:Turn each task into a line, assuming that task I processes a a[x] point on a machine, on a B machine for b[y] points, connect a[x] and B[y],Cover all edges with the fewest points in a machine and B machine (all tasks are done in a minimal mode).This is the minimum point coverage pr
Task:control Flow oriented Coverage Test proceduresIn the so-called branch coverage test, the test case quantity for a program P is compiled so, each edge of the control Flow graph of P (see, for example, Fig. 1:you already know an equivalent representation as a program flowchart) at least Once, so all condition/branch at least once to true and (possibly in another test case) are evaluated too wrong at LEAs
Every time a new version is shipped, it is often asked if the test is over. Do you have confidence in quality? What are the criteria you are basing on?
I think a lot of people will find it difficult to answer this question. Basically, you can decide whether the test can be completed according to the following five conditions.
1. Boss decides
Basically, the boss is invincible. He said when it was time. I think we will not, and dare not disagree. Xd
2. The team has a consensus to stop

For example, creating an index Idx_name_age (name,age), typically where age=50 or where age>50, is not used to idx_a_b.

Jacoco is a Java Code Coverage statistics tool, see: http://www.eclemma.org/jacoco/
Jacoco is a free Code coverage library for Java, which has been created from the Eclemma team based on the lessons learned F Rom using and integration existing libraries for many years.
Note
Jacoco weaves a additional field named $jacocoData into the inspected classes.

Whether it is unit testing, API testing, or functional testing, the code of the product is eventually called. How to evaluate the efficiency of these tests and whether all or most of the code of the product is covered? At this time, code coverage is a valuable reference indicator.Generally, code coverage is used in the following aspects:
Find out the places where the code is not tested;
Add new test code
Code coverage is an important indicator that reflects the coverage of test cases to tested software. It is also an important indicator to measure the testing progress. It is also an important indicator for Testing. Testing is often not as exciting as development. One of the important reasons is that testing is difficult to quantify, code coverage is an important
