Neuware - Property-based testing helps you create better, more solid tests with little code. By using the PropEr framework in both Erlang and Elixir, this book teaches you how to automatically generate test cases, test stateful programs, and change how you design your software for more principled and reliable approaches. You will be able to better explore the problem space, validate the assumptions you make when coming up with program behavior, and expose unexpected weaknesses in your design. PropEr will even show you how to reproduce the bugs it found. With this book, you will be writing efficient property-based tests in no time.Most tests only demonstrate that the code behaves how the developer expected it to behave, and therefore carry the same blind spots as their authors when special conditions or edge cases show up. Learn how to see things differently with property tests written in PropEr.Start with the basics of property tests, such as writing stateless properties, and using the default generators to generate test cases automatically. More importantly, learn how to think in properties. Improve your properties, write custom data generators, and discover what your code can or cannot do. Learn when to use property tests and when to stick with example tests with real-world sample projects. Explore various testing approaches to find the one that's best for your code. Shrink failing test cases to their simpler expression to highlight exactly what breaks in your code, and generate highly relevant data through targeted properties. Uncover the trickiest bugs you can think of with nearly no code at all with two special types of properties based on state transitions and finite state machines.Write Erlang and Elixir properties that generate the most effective tests you'll see, whether they are unit tests or complex integration and system tests.What You Need- Basic knowledge of Erlang, optionally Elixir- >= 20.0, with Rebar >= 3.4.0- >= 20.0, Elixir >= 1.5.0.…

Terms of sale
General Terms and Conditions and Customer Information / Privacy Policy
I. General Terms and Conditions
§ 1 Basic provisions
(1) The following terms and conditions apply to all contracts that you conclude with us as a provider (AHA-BUCH GmbH) via the Internet platforms AbeBooks and/or ZVAB. Unless otherwise agreed, the inclusion of any of your own terms and conditions used by you will be objected to
(2) A consumer within the meaning of the following regulations is any natural person who concludes a legal transaction for purposes that can predominantly be attributed neither to their commercial nor their independent professional activity. An entrepreneur is any natural or legal person or a partnership with legal capacity who, when concluding a legal transaction, acts in the exercise of his independent professional or commercial activity.
§ 2 Conclusion of the contract
(1) The object of the contract is the sale of goods.
(2) If an article is listed by us at AbeBooks or ZVAB, the activation of the offer page at AbeBooks or ZVAB constitutes the binding offer to conclude a contract under the conditions contained in the article page.
(3) The contract is concluded via the online shopping cart system as follows:
The goods intended for purchase are stored in the "shopping cart". Via the corresponding button in the navigation bar you can call up the "shopping cart" and make changes there at any time.
After calling up the "Checkout" page and entering the personal data as well as the payment and shipping conditions, all order data will be displayed again on the order overview page.
Before sending the order, you have the option of checking all information again, changing it (also via the "back" function of the Internet browser) or cancelling the purchase.
By submitting the order via the "Buy now" button, you declare the acceptance of the offer in a legally binding manner, whereby the contract is concluded.
(4) The processing of the order and transmission of all information required in connection with the conclusion of the contract is partly automated by e-mail. You must therefore ensure that the e-mail address you have stored with us is correct, that the receipt of the e-mails is technically ensured and, in particular, that spam filters do not prevent it.
§ 3 Right of retention, retention of title
(1) You can only exercise a right of retention if it concerns claims from the same contractual relationship.
(2) The goods remain our property until full payment of the purchase price.
§ 4 Warranty
(1) The statutory warranty rights exist.
(2) In the case of used goods, the warranty period is one year from delivery of the item, deviating from the statutory regulation. The shortening of the deadline does not apply:
- culpably caused damages attributable to us from injury to life, limb or health and in the case of other damages caused intentionally or through gross negligence;
- insofar as we have fraudulently concealed the defect or have assumed a guarantee for the quality of the item.
(3) As a consumer, you are requested to check the item immediately upon delivery for completeness, obvious defects and transport damage and to inform us and the freight forwarder of any complaints as soon as possible. If you do not comply with this, this will have no effect on your statutory warranty claims.
§ 5 Choice of law, place of performance, place of jurisdiction
(1) German law shall apply. In the case of consumers, this choice of law shall only apply insofar as this does not withdraw the protection afforded by mandatory provisions of the law of the state of the consumer's habitual residence (principle of favourability).
(2) The place of performance for all services arising from the existing business relationships with us as well as the place of jurisdiction is our registered office, insofar as you are not a consumer, but a merchant, a legal entity under public law or a special fund under public law. The same applies if you do not have a general place of jurisdiction in Germany or the EU or if the domicile or habitual residence is not known at the time the action is brought. The right to appeal to the court at another statutory place of jurisdiction remains unaffected by this.
(3) The provisions of the UN Convention on Contracts for the International Sale of Goods shall expressly not apply.
