fr.cnes.sirius.patrius.tools.validationTool.Validate

public class Validate
extends org.junit.Assert

The purpose of this class is to automate the logging of deviations in order to see their evolution. This way, the developers can more easily ensure that a class is still valid even if its components or the classes it uses evolve. This is an extension of the continuous integration to validation.

For each useful method of Assert, Validate provides an implementation that will compute and store the deviation, then call the Assert method. At the end of the test (usually in an @AfterClass method), produceLog() has to be called, otherwise the validation results are not written.

This class is intended as a replacement of the org.junit.Assert class for validation purposes. Its use is similar to the Assert methods of JUnit.

Concurrency :

not thread-safe

Concurrency comment :

two threads can add in the same time their computed deviations instead of adding them one after the other one

Constructor Detail

Validate

public Validate(Class<?> testClassIn)
         throws IOException

constructor of the Validate object. Uses the properties file which path is given. The resource is first searched in the classpath, then outside. Therefore, a resource in the classpath might hide a resource ouside of it, but it is highly unlikely.

Parameters:

testClassIn - the test class, which name will be stored to be printed in the logs.

Throws:

IOException - if an error occurs during the reading of the file

Since:

1.0

Method Detail

assertEquals

public final void assertEquals(double actual,
                               double nonRegExpected,

                               String deviationDescription)

Works as a replacement to the Assert.assertEquals(double, double, double) method. Compute the deviation and store it to be put in the logs by the produceLogs method. If the test fails, the deviation is still stored, but " : test failed" is added to the message.

Parameters:

actual - the value obtained in the test

nonRegExpected - the value expected by the non-regression reference

nonRegEps - the epsilon allowed with regard to the non-regression reference

externalRefExpected - the value expected by the external reference

externalRefEps - the epsilon allowed with regard to the external reference

deviationDescription - the description of the deviation

Returns true if both arguments are equal or within the range of allowed error (inclusive). Two float numbers are considered equal if there are (maxUlps - 1) (or fewer) floating point numbers between them, i.e. two adjacent floating point numbers are considered equal. Adapted from Bruce Dawson

x - first value

y - second value

maxUlps - (maxUlps - 1) is the number of floating point values between x and y.

Returns:

true if there are fewer than maxUlps floating point values between x and y.

Returns true if there is no double value strictly between the arguments or the reltaive difference between them is smaller or equal to the given tolerance. (method from Commons-Math).

Parameters:

x - First value.

y - Second value.

eps - Amount of allowed relative error.

Returns:

true if the values are two adjacent floating point numbers or they are within range of each other.
