These two are both tools of software quality but from different toolboxes of different paradigms. In summary assert is a Software testing tool which takes a corrective approach, whereas require is a design by contract tool which takes a preventive approach. Both require and assert are means of controlling validity of state. Historically there were 2 distinct paradigms for dealing with invalid states.
The release of Solidity version 0.4.10 introduced the assert(), require() and revert() functions, and confusion has reigned ever since.. In particular, the assert() and require() “guard” functions improve the readability of contract code, but differentiating between them can be quite confounding. This is the documentation for the Scala standard library. Package structure .
Scala uses singleton object, which is essentially class with only one object in the source file. Here you don,t require to mention data type and function return type explicitly. Scala is enough smart to deduce the type of data. In Scala evaluation is lazy by default.

The aims of the project The Kojo. project is lead by Lalit Pant at Kogics in India [12] and the Scala project is lead by Prof. The data sample was too small to allow for strong assertions.
Program to illustrate the working of unit type 2017-12-08 · assert and require. Solidity assert and require are convenience functions that check for conditions.
In Scala, there are no static variables or methods. Scala uses singleton object, which is essentially class with only one object in the source file. Here you don,t require to mention data type and function return type explicitly. Scala is enough smart to deduce the type of data. In Scala evaluation is lazy by default.
This behavior is provided by the assert method defined in object Predef, whose members are implicitly imported into every Scala source file. ScalaTest provides a domain specific language (DSL) for expressing assertions in tests using the word should . Se hela listan på alvinalexander.com assert也可带两个参数，表达式assert(condition, explanation) 会测试condition，如果条件不成立，会抛出含有指定explanation作为说明的AssertionError。 explanation的类型是Any，所以可以把任何对象当作说明参数。 def assert(o: scala.Option[java.lang.String], clue: Any) : Unit Assert that an Option[String] is None.If the condition is None, this method returns normally.Else, it throws TestFailedException with the String value of the Some, as well as the String obtained by invoking toString on the specified message, included in the TestFailedException's detail message. The Python assert keyword tests if a condition is true. If a condition is false, the program will stop with an optional message. Assert statements are used to debug code and handle errors. You should not use an assert statement in a production environment.
